+Etherboot/NILO i386 initialisation path and external call interface
+===================================================================
+
+1. Background
+
+GCC compiles 32-bit code.  It is capable of producing
+position-independent code, but the resulting binary is about 25%
+bigger than the corresponding fixed-position code.  Since one main use
+of Etherboot is as firmware to be burned into an EPROM, code size must
+be kept as small as possible.
+
+This means that we want to compile fixed-position code with GCC, and
+link it to have a predetermined start address.  The problem then is
+that we must know the address that the code will be loaded to when it
+runs.  There are several ways to solve this:
+
+1. Pick an address, link the code with this start address, then make
+   sure that the code gets loaded at that location.  This is
+   problematic, because we may pick an address that we later end up
+   wanting to use to load the operating system that we're booting.
+
+2. Pick an address, link the code with this start address, then set up
+   virtual addressing so that the virtual addresses match the
+   link-time addresses regardless of the real physical address that
+   the code is loaded to.  This enables us to relocate Etherboot to
+   the top of high memory, where it will be out of the way of any
+   loading operating system.
+
+3. Link the code with a text start address of zero and a data start
+   address also of zero.  Use 16-bit real mode and the
+   quasi-position-independence it gives you via segment addressing.
+   Doing this requires that we generate 16-bit code, rather than
+   32-bit code, and restricts us to a maximum of 64kB in each segment.
+
+There are other possible approaches (e.g. including a relocation table
+and code that performs standard dynamic relocation), but the three
+options listed above are probably the best available.
+
+Etherboot can be invoked in a variety of ways (ROM, floppy, as a PXE
+NBP, etc).  Several of these ways involve control being passed to
+Etherboot with the CPU in 16-bit real mode.  Some will involve the CPU
+being in 32-bit protected mode, and there's an outside chance that
+some may involve the CPU being in 16-bit protected mode.  We will
+almost certainly have to effect a CPU mode change in order to reach
+the mode we want to be in to execute the C code.
+
+Additionally, Etherboot may wish to call external routines, such as
+BIOS interrupts, which must be called in 16-bit real mode.  When
+providing a PXE API, Etherboot must provide a mechanism for external
+code to call it from 16-bit real mode.
+
+Not all i386 builds of Etherboot will want to make real-mode calls.
+For example, when built for LinuxBIOS rather than the standard PCBIOS,
+no real-mode calls are necessary.
+
+For the ultimate in PXE compatibility, we may want to build Etherboot
+to run permanently in real mode.
+
+There is a wide variety of potential combinations of mode switches
+that we may wish to implement.  There are additional complications,
+such as the inability to access a high-memory stack when running in
+real mode.
+
+2. Transition libraries
+
+To handle all these various combinations of mode switches, we have
+several "transition" libraries in Etherboot.  We also have the concept
+of an "internal" and an "external" environment.  The internal
+environment is the environment within which we can execute C code.
+The external environment is the environment of whatever external code
+we're trying to interface to, such as the system BIOS or a PXE NBP.
+
+As well as having a separate addressing scheme, the internal
+environment also has a separate stack.
+
+The transition libraries are:
+
+a) librm
+
+librm handles transitions between an external 16-bit real-mode
+environment and an internal 32-bit protected-mode environment with
+virtual addresses.
+
+b) libkir
+
+libkir handles transitions between an external 16-bit real-mode (or
+16:16 or 16:32 protected-mode) environment and an internal 16-bit
+real-mode (or 16:16 protected-mode) environment.
+
+c) libpm
+
+libpm handles transitions between an external 32-bit protected-mode
+environment with flat physical addresses and an internal 32-bit
+protected-mode environment with virtual addresses.
+
+The transition libraries handle the transitions required when
+Etherboot is started up for the first time, the transitions required
+to execute any external code, and the transitions required when
+Etherboot exits (if it exits).  When Etherboot provides a PXE API,
+they also handle the transitions required when a PXE client makes a
+PXE API call to Etherboot.
+
+Etherboot may use multiple transition libraries.  For example, an
+Etherboot ELF image does not require librm for its initial transitions
+from prefix to runtime, but may require librm for calling external
+real-mode functions.
+
+3. Setup and initialisation
+
+Etherboot is conceptually divided into the prefix, the decompressor,
+and the runtime image.  (For non-compressed images, the decompressor
+is a no-op.)  The complete image comprises all three parts and is
+distinct from the runtime image, which exclude the prefix and the
+decompressor.
+
+The prefix does several tasks:
+
+  Load the complete image into memory.  (For example, the floppy
+  prefix issues BIOS calls to load the remainder of the complete image
+  from the floppy disk into RAM, and the ISA ROM prefix copies the ROM
+  contents into RAM for faster access.)
+
+  Call the decompressor, if the runtime image is compressed.  This
+  decompresses the runtime image.
+
+  Call the runtime image's setup() routine.  This is a routine
+  implemented in assembly code which sets up the internal environment
+  so that C code can execute.
+
+  Call the runtime image's arch_initialise() routine.  This is a
+  routine implemented in C which does some basic startup tasks, such
+  as initialising the console device, obtaining a memory map and
+  relocating the runtime image to high memory.
+
+  Call the runtime image's arch_main() routine.  This records the exit
+  mechanism requested by the prefix and calls main().  (The prefix
+  needs to register an exit mechanism because by the time main()
+  returns, the memory occupied by the prefix has most likely been
+  overwritten.)
+
+When acting as a PXE ROM, the ROM prefix contains an UNDI loader
+routine in addition to its usual code.  The UNDI loader performs a
+similar sequence of steps:
+
+  Load the complete image into memory.
+
+  Call the decompressor.
+
+  Call the runtime image's setup() routine.
+
+  Call the runtime image's arch_initialise() routine.
+
+  Call the runtime image's install_pxe_stack() routine.
+
+  Return to caller.
+
+The runtime image's setup() routine will perform the following steps:
+
+  Switch to the internal environment using an appropriate transition
+  library.  This will record the parameters of the external
+  environment.
+
+  Set up the internal environment: load a stack, and set up a GDT for
+  virtual addressing if virtual addressing is to be used.
+
+  Switch back to the external environment using the transition
+  library.  This will record the parameters of the internal
+  environment.
+
+Once the setup() routine has returned, the internal environment has been
+set up ready for C code to run.  The prefix can call C routines using
+a function from the transition library.
+
+The runtime image's arch_initialise() routine will perform the
+following steps:
+
+  Zero the bss
+
+  Initialise the console device(s) and print a welcome message.
+
+  Obtain a memory map via the INT 15,E820 BIOS call or suitable
+  fallback mechanism. [not done if libkir is being used]
+
+  Relocate the runtime image to the top of high memory. [not done if
+  libkir is being used]
+
+  Install librm to base memory. [done only if librm is being used]
+
+  Call initialise().
+
+  Return to the prefix, setting registers to indicate to the prefix
+  the new location of the transition library, if applicable.  Which
+  registers these are is specific to the transition library being
+  used.
+
+Once the arch_initialise() routine has returned, the prefix will
+probably call arch_main().

+ * @v netdev		Network device
+ *
+ * Fun, fun, fun.  UNDI drivers don't use polling; they use
+ * interrupts.  We therefore cheat and pretend that an interrupt has
+ * occurred every time undinet_poll() is called.  This isn't too much
+ * of a hack; PCI devices share IRQs and so the first thing that a
+ * proper ISR should do is call PXENV_UNDI_ISR to determine whether or
+ * not the UNDI NIC generated the interrupt; there is no harm done by
+ * spurious calls to PXENV_UNDI_ISR.  Similarly, we wouldn't be
+ * handling them any more rapidly than the usual rate of
+ * undinet_poll() being called even if we did implement a full ISR.
+ * So it should work.  Ha!
+ *
+ * Addendum (21/10/03).  Some cards don't play nicely with this trick,
+ * so instead of doing it the easy way we have to go to all the hassle
+ * of installing a genuine interrupt service routine and dealing with
+ * the wonderful 8259 Programmable Interrupt Controller.  Joy.
+ *
+ * Addendum (10/07/07).  When doing things such as iSCSI boot, in
+ * which we have to co-operate with a running OS, we can't get away
+ * with the "ISR-just-increments-a-counter-and-returns" trick at all,
+ * because it involves tying up the PIC for far too long, and other
+ * interrupt-dependent components (e.g. local disks) start breaking.
+ * We therefore implement a "proper" ISR which calls PXENV_UNDI_ISR
+ * from within interrupt context in order to deassert the device
+ * interrupt, and sends EOI if applicable.

+
+@section pxe_routing IP routing
+
+Several PXE API calls (e.g. pxenv_tftp_open() and pxenv_udp_write())
+allow for the caller to specify a "relay agent IP address", often in a
+field called "gateway" or similar.  The PXE specification states that
+"The IP layer should provide space for a minimum of four routing
+entries obtained from the default router and static route DHCP option
+tags in the DHCPACK message, plus any non-zero giaddr field from the
+DHCPOFFER message(s) accepted by the client".
+
+The DHCP static route option ("option static-routes" in dhcpd.conf)
+works only for classed IP routing (i.e. it provides no way to specify
+a subnet mask).  Since virtually everything now uses classless IP
+routing, the DHCP static route option is almost totally useless, and
+is (according to the dhcp-options man page) not implemented by any of
+the popular DHCP clients.
+
+This leaves the caller-specified "relay agent IP address", the giaddr
+field from the DHCPOFFER message(s) and the default gateway(s)
+provided via the routers option ("option routers" in dhcpd.conf) in
+the DHCPACK message.  Each of these is a default gateway address.
+It's a fair bet that the routers option should take priority over the
+giaddr field, since the routers option has to be explicitly specified
+by the DHCP server operator.  Similarly, it's fair to assume that the
+caller-specified "relay agent IP address", if present, should take
+priority over any other routing table entries.
+
+@bug Etherboot currently ignores all potential sources of routing
+information other than the first router provided to it by a DHCP
+routers option.
+
+@section pxe_x86_modes x86 processor mode restrictions
+
+On the x86 platform, different PXE API calls have different
+restrictions on the processor modes (real or protected) that can be
+used.  See the individual API call descriptions for the restrictions
+that apply to any particular call.
+
+@subsection pxe_x86_pmode16 Real mode, or protected-mode with 16-bit stack
+
+The PXE specification states that the API function can be called in
+protected mode only if the s_PXE::StatusCallout field is set to a
+non-zero value, and that the API function cannot be called with a
+32-bit stack segment.
+
+Etherboot does not enforce either of these restrictions; they seem (as
+with so much of the PXE specification) to be artifacts of the Intel
+implementation.

+ * Declaration of variables in .data16
+ *
+ * To place a variable in the .data16 segment, declare it using the
+ * pattern:
+ *
+ *   int __data16 ( foo );
+ *   #define foo __use_data16 ( foo );
+ *
+ *   extern uint32_t __data16 ( bar );
+ *   #define bar __use_data16 ( bar );
+ *
+ *   static long __data16 ( baz ) = 0xff000000UL;
+ *   #define baz __use_data16 ( baz );
+ *
+ * i.e. take a normal declaration, add __data16() around the variable
+ * name, and add a line saying "#define <name> __use_data16 ( <name> )
+ *
+ * You can then access them just like any other variable, for example
+ *
+ *   int x = foo + bar;
+ *
+ * This magic is achieved at a cost of only around 7 extra bytes per
+ * group of accesses to .data16 variables.  When using KEEP_IT_REAL,
+ * there is no extra cost.
+ *
+ * You should place variables in .data16 when they need to be accessed
+ * by real-mode code.  Real-mode assembly (e.g. as created by
+ * REAL_CODE()) can access these variables via the usual data segment.
+ * You can therefore write something like
+ *
+ *   static uint16_t __data16 ( foo );
+ *   #define foo __use_data16 ( foo )
+ *
+ *   int bar ( void ) {
+ *     __asm__ __volatile__ ( REAL_CODE ( "int $0xff\n\t"
+ *                                        "movw %ax, foo" )
+ *                            : : );
+ *     return foo;
+ *   }
+ *
+ * Variables may also be placed in .text16 using __text16 and
+ * __use_text16.  Some variables (e.g. chained interrupt vectors) fit
+ * most naturally in .text16; most should be in .data16.
+ *
+ * If you have only a pointer to a magic symbol within .data16 or
+ * .text16, rather than the symbol itself, you can attempt to extract
+ * the underlying symbol name using __from_data16() or
+ * __from_text16().  This is not for the faint-hearted; check the
+ * assembler output to make sure that it's doing the right thing.

+ * connection with pxenv_tftp_open().  The data written into
+ * s_PXENV_TFTP_READ::Buffer is just the file data; the various
+ * network headers have already been removed.
+ *
+ * The buffer must be large enough to contain a packet of the size
+ * negotiated via the s_PXENV_TFTP_OPEN::PacketSize field in the
+ * pxenv_tftp_open() call.  It is worth noting that the PXE
+ * specification does @b not require the caller to fill in
+ * s_PXENV_TFTP_READ::BufferSize before calling pxenv_tftp_read(), so
+ * the PXE stack is free to ignore whatever value the caller might
+ * place there and just assume that the buffer is large enough.  That
+ * said, it may be worth the caller always filling in
+ * s_PXENV_TFTP_READ::BufferSize to guard against PXE stacks that
+ * mistake it for an input parameter.
+ *
+ * The length of the TFTP data packet will be returned via
+ * s_PXENV_TFTP_READ::BufferSize.  If this length is less than the
+ * blksize negotiated via s_PXENV_TFTP_OPEN::PacketSize in the call to
+ * pxenv_tftp_open(), this indicates that the block is the last block
+ * in the file.  Note that zero is a valid length for
+ * s_PXENV_TFTP_READ::BufferSize, and will occur when the length of
+ * the file is a multiple of the blksize.
+ *
+ * The PXE specification doesn't actually state that calls to
+ * pxenv_tftp_read() will return the data packets in strict sequential
+ * order, though most PXE stacks will probably do so.  The sequence
+ * number of the packet will be returned in
+ * s_PXENV_TFTP_READ::PacketNumber.  The first packet in the file has
+ * a sequence number of one, not zero.
+ *
+ * To guard against flawed PXE stacks, the caller should probably set
+ * s_PXENV_TFTP_READ::PacketNumber to one less than the expected
+ * returned value (i.e. set it to zero for the first call to
+ * pxenv_tftp_read() and then re-use the returned s_PXENV_TFTP_READ
+ * parameter block for subsequent calls without modifying
+ * s_PXENV_TFTP_READ::PacketNumber between calls).  The caller should
+ * also guard against potential problems caused by flawed
+ * implementations returning the occasional duplicate packet, by
+ * checking that the value returned in s_PXENV_TFTP_READ::PacketNumber
+ * is as expected (i.e. one greater than that returned from the
+ * previous call to pxenv_tftp_read()).
+ *
+ * On x86, you must set the s_PXE::StatusCallout field to a nonzero

+ * pointed to by s_PXENV_TFTP_READ_FILE::Buffer.
+ *
+ * The PXE specification does not make it clear how the caller
+ * requests that MTFTP be used rather than TFTP (or vice versa).  One
+ * reasonable guess is that setting
+ * s_PXENV_TFTP_READ_FILE::McastIPAddress to 0.0.0.0 would cause TFTP
+ * to be used instead of MTFTP, though it is conceivable that some PXE
+ * stacks would interpret that as "use the DHCP-provided multicast IP
+ * address" instead.  Some PXE stacks will not implement MTFTP at all,
+ * and will always use TFTP.
+ *
+ * It is not specified whether or not
+ * s_PXENV_TFTP_READ_FILE::TFTPSrvPort will be used as the TFTP server
+ * port for TFTP (rather than MTFTP) downloads.  Callers should assume
+ * that the only way to access a TFTP server on a non-standard port is
+ * to use pxenv_tftp_open() and pxenv_tftp_read().
+ *
+ * If s_PXENV_TFTP_READ_FILE::GatewayIPAddress is 0.0.0.0, normal IP
+ * routing will take place.  See the relevant
+ * @ref pxe_routing "implementation note" for more details.
+ *
+ * It is interesting to note that s_PXENV_TFTP_READ_FILE::Buffer is an
+ * #ADDR32_t type, i.e. nominally a flat physical address.  Some PXE
+ * NBPs (e.g. NTLDR) are known to call pxenv_tftp_read_file() in real
+ * mode with s_PXENV_TFTP_READ_FILE::Buffer set to an address above
+ * 1MB.  This means that PXE stacks must be prepared to write to areas
+ * outside base memory.  Exactly how this is to be achieved is not
+ * specified, though using INT 15,87 is as close to a standard method
+ * as any, and should probably be used.  Switching to protected-mode
+ * in order to access high memory will fail if pxenv_tftp_read_file()
+ * is called in V86 mode; it is reasonably to expect that a V86
+ * monitor would intercept the relatively well-defined INT 15,87 if it
+ * wants the PXE stack to be able to write to high memory.
+ *
+ * Things get even more interesting if pxenv_tftp_read_file() is
+ * called in protected mode, because there is then absolutely no way
+ * for the PXE stack to write to an absolute physical address.  You
+ * can't even get around the problem by creating a special "access
+ * everything" segment in the s_PXE data structure, because the
+ * #SEGDESC_t descriptors are limited to 64kB in size.
+ *
+ * Previous versions of the PXE specification (e.g. WfM 1.1a) provide
+ * a separate API call, %pxenv_tftp_read_file_pmode(), specifically to
+ * work around this problem.  The s_PXENV_TFTP_READ_FILE_PMODE
+ * parameter block splits s_PXENV_TFTP_READ_FILE::Buffer into
+ * s_PXENV_TFTP_READ_FILE_PMODE::BufferSelector and
+ * s_PXENV_TFTP_READ_FILE_PMODE::BufferOffset, i.e. it provides a
+ * protected-mode segment:offset address for the data buffer.  This
+ * API call is no longer present in version 2.1 of the PXE
+ * specification.
+ *
+ * Etherboot makes the assumption that s_PXENV_TFTP_READ_FILE::Buffer
+ * is an offset relative to the caller's data segment, when
+ * pxenv_tftp_read_file() is called in protected mode.
+ *
+ * On x86, you must set the s_PXE::StatusCallout field to a nonzero
+ * value before calling this function in protected mode.  You cannot

+Build using this command line:
+
+make CONFIG=vbox bin/intel--virtio-net--pcnet32.isarom
+
+Max size of a VirtualBox ROM is 56KB, 57344 bytes. There should be no need
+to pad the image as long as the binary is smaller or equal to this size.
+
+To use the ROM in VirtualBox you need to enable it using this command:
+
+vboxmanage setextradata global \
+    VBoxInternal/Devices/pcbios/0/Config/LanBootRom \
+    /absolute/path/to/intel--virtio-net--pcnet32.isarom
+
+NB: If you build the ROM using the .rom prefix then it'll be built as a PCI
+ROM, which won't work properly in VirtualBox.  The error message you'll see
+is "No more network devices", which is somewhat confusing.  If you enter the
+shell and use the "autoboot" command things will work as intended.  Remember
+to always build as a .isarom to avoid this issue.

+/** @page build_sys Build system
+
+@section overview Overview
+
+Building an Etherboot image consists of three stages:
+
+  -# @ref compilation : Compiling all the source files into object files
+  -# @ref linking : Linking a particular image from selected object files
+  -# @ref finalisation : Producing the final output binary
+
+Though this is a remarkably complex process, it is important to note
+that it all happens automatically.  Whatever state your build tree is
+in, you can always type, for example
+
+@code
+
+	make bin/rtl8139.dsk
+
+@endcode
+
+and know that you will get a floppy disk image with an RTL8139 driver
+built from the current sources.
+
+@section compilation Compilation
+
+@subsection comp_overview Overview
+
+Each source file (a @c .c or a @c .S file) is compiled into a @c .o
+file in the @c bin/ directory.  Etherboot makes minimal use of
+conditional compilation (see @ref ifdef_harmful), and so you will find
+that all objects get built, even the objects that correspond to
+features that you are not intending to include in your image.  For
+example, all network card drivers will be compiled even if you are
+just building a ROM for a 3c509 card.  This is a deliberate design
+decision; please do @b not attempt to "fix" the build system to avoid
+doing this.
+
+Source files are defined to be any @c .c or @c .S files found in a
+directory listed in the Makefile variable #SRCDIRS.  You therefore do
+@b not need to edit the Makefile just because you have added a new
+source file (although you will need to edit the Makefile if you have
+added a new source directory).  To see a list of all source
+directories and source files that the build system currently knows
+about, you can use the commands
+
+@code
+
+	make srcdirs
+	make srcs
+
+@endcode
+
+Rules for compiling @c .c and @c .S files are defined in the Makefile
+variables #RULE_c and #RULE_S.  Makefile rules are automatically
+generated for each source file using these rules.  The generated rules
+can be found in the @c .d file corresponding to each source file;
+these are located in <tt>bin/deps/</tt>.  For example, the rules
+generated for <tt>drivers/net/rtl8139.c</tt> can be found in
+<tt>bin/deps/drivers/net/rtl8139.c.d</tt>.  These rules allow you to
+type, for example
+
+@code
+
+	make bin/rtl8139.o
+
+@endcode
+
+and have <tt>rtl8139.o</tt> be built from
+<tt>drivers/net/rtl8139.c</tt> using the generic rule #RULE_c for
+compiling @c .c files.
+
+You can see the full list of object files that will be built using
+
+@code
+
+	make bobjs
+
+@endcode
+
+@subsection comp_ar After compilation
+
+Once all objects have been compiled, they will be collected into a
+build library ("blib") in <tt>bin/blib.a</tt>.
+
+@subsection comp_custom Customising compilation
+
+The Makefile rules for a particular object can be customised to a
+certain extent by defining the Makefile variable CFLAGS_@<object@>.
+For example, if you were to set
+
+@code
+
+	CFLAGS_rtl8139 = -DFOO
+
+@endcode
+
+then <tt>bin/rtl8139.o</tt> would be compiled with the additional
+flags <tt>-DFOO</tt>.  To see the flags that will be used when
+compiling a particular object, you can use e.g.
+
+@code
+
+	make bin/rtl8139.flags
+
+@endcode
+
+If you need more flexibility than the CFLAGS_@<object@> mechanism
+provides, then you can exclude source files from the automatic rule
+generation process by listing them in the Makefile variable
+#NON_AUTO_SRCS.  The command
+
+@code
+
+	make autosrcs
+
+@endcode
+
+will show you which files are currently part of the automatic rule
+generation process.
+
+@subsection comp_multiobj Multiple objects
+
+A single source file can be used to generate multiple object files.
+This is used, for example, to generate the decompressing and the
+non-decompressing prefixes from the same source files.
+
+By default, a single object will be built from each source file.  To
+override the list of objects for a source file, you can define the
+Makefile variable OBJS_@<object@>.  For example, the
+<tt>arch/i386/prefix/dskprefix.S</tt> source file is built into two
+objects, <tt>bin/dskprefix.o</tt> and <tt>zdskprefix.o</tt> by
+defining the Makefile variable
+
+@code
+
+	OBJS_dskprefix = dskprefix zdskprefix
+
+@endcode
+
+Since there would be little point in building two identical objects,
+customised compilation flags (see @ref comp_custom) are defined as
+
+@code
+
+	CFLAGS_zdskprefix = -DCOMPRESS
+
+@endcode
+
+Thus, <tt>arch/i386/prefix/dskprefix.S</tt> is built into @c
+dskprefix.o using the normal set of flags, and into @c zdskprefix.o
+using the normal set of flags plus <tt>-DCOMPRESS</tt>.
+
+@subsection comp_debug Special debugging targets
+
+In addition to the basic rules #RULE_c and #RULE_S for compiling
+source files into object files, there are various other rules that can
+be useful for debugging.
+
+@subsubsection comp_debug_c_to_c Preprocessed C
+
+You can see the results of preprocessing a @c .c file (including the
+per-object flags defined via CFLAGS_@<object@> if applicable) using
+e.g.
+
+@code
+
+	make bin/rtl8139.c
+
+@endcode
+
+and examining the resulting file (<tt>bin/rtl8139.c</tt> in this
+case).
+
+@subsubsection comp_debug_x_to_s Assembler
+
+You can see the results of assembling a @c .c file, or of
+preprocessing a @c .S file, using e.g.
+
+@code
+
+	make bin/rtl8139.s
+	make bin/zdskprefix.s
+
+@endcode
+
+@subsubsection comp_debug_dbg Debugging-enabled targets
+
+You can build targets with debug messages (DBG()) enabled using e.g.
+
+@code
+
+	make bin/rtl8139.dbg.o
+	make bin/rtl8139.dbg2.o
+
+@endcode
+
+You will probably not need to use these targets directly, since a
+mechanism exists to select debugging levels at build time; see @ref
+debug.
+
+@section linking Linking
+
+@subsection link_overview Overview
+
+Etherboot is designed to be small and extremely customisable.  This is
+achieved by linking in only the features that are really wanted in any
+particular build.
+
+There are two places from which the list of desired features is
+obtained:
+
+  -# @ref link_config_h
+  -# @ref link_cmdline
+
+@subsection link_config_h config.h
+
+The config.h file is used to define global build options that are
+likely to apply to all images that you build, such as the console
+types, supported download protocols etc.  See the documentation for
+config.h for more details.
+
+@subsection link_cmdline The make command line
+
+When you type a command such as
+
+@code
+
+	make bin/dfe538.zrom
+
+@endcode
+
+it is used to derive the following information:
+
+   - We are building a compressed ROM image
+   - The DFE538 is a PCI NIC, so we need the decompressing PCI ROM prefix
+   - The PCI IDs for the DFE538 are 1186:1300
+   - The DFE538 is an rtl8139-based card, therefore we need the rtl8139 driver
+
+You can see this process in action using the command
+
+@code
+
+	make bin/dfe538.zrom.info
+

+
+This should be interpreted as follows:
+
+@code
+
+	Elements             : dfe538
+	Prefix               : zrom
+
+@endcode
+
+"Elements" is the list of components preceding the first dot in the
+target name.  "Prefix" is the component following the first dot in the
+target name.  (It's called a "prefix" because the code that makes it a
+@c .zrom (rather than a @c .dsk, @c .zpxe or any other type of target)
+usually ends up at the start of the resulting binary image.)
+
+@code
+
+	Drivers              : rtl8139
+
+@endcode
+
+"Drivers" is the list of drivers corresponding to the "Elements".
+Most drivers support several network cards.  The PCI_ROM() and
+ISA_ROM() macros are used in the driver source files to list the cards
+that a particular driver can support.
+
+@code
+
+	ROM name             : dfe538
+
+@endcode
+
+"ROM name" is the first element in the "Elements" list.  It is used to
+select the PCI IDs for a PCI ROM.
+
+@code
+
+	Media                : rom
+
+@endcode
+
+"Media" is the "Prefix" minus the leading @c z, if any.
+
+@code
+
+	ROM type             : pci
+	PCI vendor           : 0x1186
+	PCI device           : 0x1300
+
+@endcode
+
+These are derived from the "ROM name" and the PCI_ROM() or ISA_ROM()
+macros in the driver source files.
+
+@code
+
+	LD driver symbols    : obj_rtl8139
+	LD prefix symbols    : obj_zpciprefix
+
+@endcode
+
+This is the interesting part.  At this point, we have established that
+we need the rtl8139 driver (i.e. @c rtl8139.o) and the decompressing
+PCI prefix (i.e. @c zpciprefix.o).  Our build system (via the
+compiler.h header file) arranges that every object exports a symbol
+obj_@<object@>; this can be seen by e.g.
+
+@code
+
+	objdump -t bin/rtl8139.o
+
+@endcode
+
+which will show the line
+
+@code
+
+	00000000 g       *ABS*  00000000 obj_rtl8139
+
+@endcode
+
+By instructing the linker that we need the symbols @c obj_rtl8139 and
+@c obj_zpciprefix, we can therefore ensure that these two objects are
+included in our build.  (The linker will also include any objects that
+these two objects require, since that's the whole purpose of the
+linker.)
+
+In a similar way, we always instruct the linker that we need the
+symbol @c obj_config, in order to include the object @c config.o.  @c
+config.o is used to drag in the objects that were specified via
+config.h; see @ref link_config_h.
+
+@code
+
+	LD target flags      :  -u obj_zpciprefix --defsym check_obj_zpciprefix=obj_zpciprefix   -u obj_rtl8139 --defsym check_obj_rtl8139=obj_rtl8139   -u obj_config --defsym check_obj_config=obj_config  --defsym pci_vendor_id=0x1186 --defsym pci_device_id=0x1300
+
+@endcode
+
+These are the flags that we pass to the linker in order to include the
+objects that we want in our build, and to check that they really get
+included.  (This latter check is needed to work around what seems to
+be a bug in @c ld).
+
+The linker does its job of linking all the required objects together
+into a coherent build.  The best way to see what is happening is to
+look at one of the resulting linker maps; try, for example
+
+@code
+
+	make bin/dfe538.dsk.map
+
+@endcode
+
+The linker map includes, amongst others:
+
+  - A list of which objects are included in the build, and why.
+  - The results of processing the linker script, line-by-line.
+  - A complete symbol table of the resulting build.
+
+It is worth spending time examining the linker map to see how an
+Etherboot image is assembled.
+
+Whatever format is selected, the Etherboot image is built into an ELF
+file, simply because this is the default format used by @c ld.
+
+@section finalisation Finalisation
+
+@subsection final_overview Overview
+
+The ELF file resulting from @ref linking "linking" needs to be
+converted into the final binary image.  Usually, this is just a case
+of running
+
+@code
+
+	objcopy -O binary <elf file> <output file>
+
+@endcode
+
+to convert the ELF file into a raw binary image.  Certain image
+formats require special additional treatment.
+
+@subsection final_rom ROM images
+
+ROM images must be rounded up to a suitable ROM size (e.g. 16kB or
+32kB), and certain header information such as checksums needs to be
+filled in.  This is done by the @c makerom.pl program.

+The driver is heavily based on the work of others are referenced in the 3c515.c file.
+
+ISA Plug and Play (ISAPNP) support has been added for Non-PNP Bioses.  The ISAPNP code requires the defination of ISA_PNP as:
+
+#define ISA_PNP
+
+Issues:
+=======
+1) RESOLVED - When ISAPNP is defined, the etherboot probe is unable to find the card during the first probe.  This is true even though the ISA PNP code actually found and activated the driver.
+
+2) RESOLVED - When ISA_PNP is defined, the etherboot probe finds the incorrect MAC address for the card. However, when the linux kernel boots and loads the linux 3c515 driver the correct MAC address is found. This means that with ISA_PNP defined, you require both MAC addresses defined in the /etc/dhcpd.conf file.  The first MAC address allows the driver to load the LTSP Linux kernel.  The second allows the Linux dhclient to resolve its IP address.
+
+3) Although the ISA PNP docs specify that the IRQ, DMA and IO Address needs to be assigned to the card before it is activated, Etherboot does not seem to care.  Therefore the code does not assign the card with these values.
+
+If you can help address any of thse issues, please feel free.

+ * v1.00pre1	2-11-1998	GRB	Got prom boot issue fixed.
+ * v2.0		9-24-1999	SCS	Modified for 3c905 (from 3c905b code)
+ *					Re-wrote poll and transmit for
+ *					better error recovery and heavy
+ *					network traffic operation
+ * v2.01    5-26-2003 NN Fixed driver alignment issue which
+ *                  caused system lockups if driver structures
+ *                  not 8-byte aligned.
+ * v2.02   11-28-2007 GSt Got polling working again by replacing

+/* Command style register access
+
+Registers CMD0, CMD2, CMD3,CMD7 and INTEN0 uses a write access technique called command style access. It allows the write to selected bits of this register without altering the bits that are not selected. Command style registers are divided into 4 bytes that can be written independently. Higher order bit of each byte is the  value bit that specifies the value that will be written into the selected bits of register. 
+
+eg., if the value 10011010b is written into the least significant byte of a command style register, bits 1,3 and 4 of the register will be set to 1, and the other bits will not be altered. If the value 00011010b is written into the same byte, bits 1,3 and 4 will be cleared to 0 and the other bits will not be altered.

+ * are introduced: 3, 2, 1, 0.5 and 0.25 MBit/s.
+ *

+ * Modulation for Atheros' Turbo G and Turbo A, its supposed to provide a
+ * throughput transmission speed up to 40Mbit/s-60Mbit/s at a 108Mbit/s
+ * signaling rate achieved through the bonding of two 54Mbit/s 802.11g
+ * channels. To use this feature your Access Point must also suport it.
+ * There is also a distinction between "static" and "dynamic" turbo modes:
+ *
+ * - Static: is the dumb version: devices set to this mode stick to it until
+ *     the mode is turned off.
+ * - Dynamic: is the intelligent version, the network decides itself if it
+ *     is ok to use turbo. As soon as traffic is detected on adjacent channels
+ *     (which would get used in turbo mode), or when a non-turbo station joins
+ *     the network, turbo mode won't be used until the situation changes again.
+ *     Dynamic mode is achieved by Atheros' Adaptive Radio (AR) feature which
+ *     monitors the used radio band in order to decide whether turbo mode may
+ *     be used or not.
+ *
+ * This article claims Super G sticks to bonding of channels 5 and 6 for
+ * USA:
+ *
+ * http://www.pcworld.com/article/id,113428-page,1/article.html
+ *
+ * The channel bonding seems to be driver specific though. In addition to
+ * deciding what channels will be used, these "Turbo" modes are accomplished
+ * by also enabling the following features:
+ *
+ * - Bursting: allows multiple frames to be sent at once, rather than pausing
+ *     after each frame. Bursting is a standards-compliant feature that can be
+ *     used with any Access Point.
+ * - Fast frames: increases the amount of information that can be sent per
+ *     frame, also resulting in a reduction of transmission overhead. It is a
+ *     proprietary feature that needs to be supported by the Access Point.
+ * - Compression: data frames are compressed in real time using a Lempel Ziv
+ *     algorithm. This is done transparently. Once this feature is enabled,
+ *     compression and decompression takes place inside the chipset, without
+ *     putting additional load on the host CPU.

+ * enum ath5k_int - Hardware interrupt masks helpers
+ *
+ * @AR5K_INT_RX: mask to identify received frame interrupts, of type
+ * 	AR5K_ISR_RXOK or AR5K_ISR_RXERR
+ * @AR5K_INT_RXDESC: Request RX descriptor/Read RX descriptor (?)
+ * @AR5K_INT_RXNOFRM: No frame received (?)
+ * @AR5K_INT_RXEOL: received End Of List for VEOL (Virtual End Of List). The
+ * 	Queue Control Unit (QCU) signals an EOL interrupt only if a descriptor's
+ * 	LinkPtr is NULL. For more details, refer to:
+ * 	http://www.freepatentsonline.com/20030225739.html
+ * @AR5K_INT_RXORN: Indicates we got RX overrun (eg. no more descriptors).
+ * 	Note that Rx overrun is not always fatal, on some chips we can continue
+ * 	operation without reseting the card, that's why int_fatal is not
+ * 	common for all chips.
+ * @AR5K_INT_TX: mask to identify received frame interrupts, of type
+ * 	AR5K_ISR_TXOK or AR5K_ISR_TXERR
+ * @AR5K_INT_TXDESC: Request TX descriptor/Read TX status descriptor (?)
+ * @AR5K_INT_TXURN: received when we should increase the TX trigger threshold
+ * 	We currently do increments on interrupt by
+ * 	(AR5K_TUNE_MAX_TX_FIFO_THRES - current_trigger_level) / 2
+ * @AR5K_INT_MIB: Indicates the Management Information Base counters should be
+ * 	checked. We should do this with ath5k_hw_update_mib_counters() but
+ * 	it seems we should also then do some noise immunity work.
+ * @AR5K_INT_RXPHY: RX PHY Error
+ * @AR5K_INT_RXKCM: RX Key cache miss
+ * @AR5K_INT_SWBA: SoftWare Beacon Alert - indicates its time to send a
+ * 	beacon that must be handled in software. The alternative is if you
+ * 	have VEOL support, in that case you let the hardware deal with things.
+ * @AR5K_INT_BMISS: If in STA mode this indicates we have stopped seeing
+ * 	beacons from the AP have associated with, we should probably try to
+ * 	reassociate. When in IBSS mode this might mean we have not received
+ * 	any beacons from any local stations. Note that every station in an
+ * 	IBSS schedules to send beacons at the Target Beacon Transmission Time
+ * 	(TBTT) with a random backoff.
+ * @AR5K_INT_BNR: Beacon Not Ready interrupt - ??
+ * @AR5K_INT_GPIO: GPIO interrupt is used for RF Kill, disabled for now
+ * 	until properly handled
+ * @AR5K_INT_FATAL: Fatal errors were encountered, typically caused by DMA
+ * 	errors. These types of errors we can enable seem to be of type
+ * 	AR5K_SIMR2_MCABT, AR5K_SIMR2_SSERR and AR5K_SIMR2_DPERR.
+ * @AR5K_INT_GLOBAL: Used to clear and set the IER
+ * @AR5K_INT_NOCARD: signals the card has been removed
+ * @AR5K_INT_COMMON: common interrupts shared amogst MACs with the same
+ * 	bit value
+ *
+ * These are mapped to take advantage of some common bits
+ * between the MACs, to be able to set intr properties
+ * easier. Some of them are not used yet inside hw.c. Most map
+ * to the respective hw interrupt value as they are common amogst different
+ * MACs.

+ *
+ * @ah: the &struct ath5k_hw
+ * @mask: the bssid_mask, a u8 array of size ETH_ALEN
+ *
+ * BSSID masking is a method used by AR5212 and newer hardware to inform PCU
+ * which bits of the interface's MAC address should be looked at when trying
+ * to decide which packets to ACK. In station mode and AP mode with a single
+ * BSS every bit matters since we lock to only one BSS. In AP mode with
+ * multiple BSSes (virtual interfaces) not every bit matters because hw must
+ * accept frames for all BSSes and so we tweak some bits of our mac address
+ * in order to have multiple BSSes.
+ *
+ * NOTE: This is a simple filter and does *not* filter out all
+ * relevant frames. Some frames that are not for us might get ACKed from us
+ * by PCU because they just match the mask.
+ *
+ * When handling multiple BSSes you can get the BSSID mask by computing the
+ * set of  ~ ( MAC XOR BSSID ) for all bssids we handle.
+ *
+ * When you do this you are essentially computing the common bits of all your
+ * BSSes. Later it is assumed the harware will "and" (&) the BSSID mask with
+ * the MAC address to obtain the relevant bits and compare the result with
+ * (frame's BSSID & mask) to see if they match.
+ */
+/*
+ * Simple example: on your card you have have two BSSes you have created with
+ * BSSID-01 and BSSID-02. Lets assume BSSID-01 will not use the MAC address.
+ * There is another BSSID-03 but you are not part of it. For simplicity's sake,
+ * assuming only 4 bits for a mac address and for BSSIDs you can then have:
+ *
+ *                  \
+ * MAC:                0001 |
+ * BSSID-01:   0100 | --> Belongs to us
+ * BSSID-02:   1001 |
+ *                  /
+ * -------------------
+ * BSSID-03:   0110  | --> External
+ * -------------------
+ *
+ * Our bssid_mask would then be:
+ *
+ *             On loop iteration for BSSID-01:
+ *             ~(0001 ^ 0100)  -> ~(0101)
+ *                             ->   1010
+ *             bssid_mask      =    1010
+ *
+ *             On loop iteration for BSSID-02:
+ *             bssid_mask &= ~(0001   ^   1001)
+ *             bssid_mask =   (1010)  & ~(0001 ^ 1001)
+ *             bssid_mask =   (1010)  & ~(1001)
+ *             bssid_mask =   (1010)  &  (0110)
+ *             bssid_mask =   0010
+ *
+ * A bssid_mask of 0010 means "only pay attention to the second least
+ * significant bit". This is because its the only bit common
+ * amongst the MAC and all BSSIDs we support. To findout what the real
+ * common bit is we can simply "&" the bssid_mask now with any BSSID we have
+ * or our MAC address (we assume the hardware uses the MAC address).
+ *
+ * Now, suppose there's an incoming frame for BSSID-03:
+ *
+ * IFRAME-01:  0110
+ *
+ * An easy eye-inspeciton of this already should tell you that this frame
+ * will not pass our check. This is beacuse the bssid_mask tells the
+ * hardware to only look at the second least significant bit and the
+ * common bit amongst the MAC and BSSIDs is 0, this frame has the 2nd LSB
+ * as 1, which does not match 0.
+ *

+ * There are some special registers on the RF chip
+ * that control various operation settings related mostly to
+ * the analog parts (channel, gain adjustment etc).
+ *
+ * We don't write on those registers directly but
+ * we send a data packet on the chip, using a special register,
+ * that holds all the settings we need. After we 've sent the
+ * data packet, we write on another special register to notify hw
+ * to apply the settings. This is done so that control registers
+ * can be dynamicaly programmed during operation and the settings
+ * are applied faster on the hw.
+ *
+ * We call each data packet an "RF Bank" and all the data we write
+ * (all RF Banks) "RF Buffer". This file holds initial RF Buffer
+ * data for the different RF chips, and various info to match RF
+ * Buffer offsets with specific RF registers so that we can access
+ * them. We tweak these settings on rfregs_init function.
+ *
+ * Also check out reg.h and U.S. Patent 6677779 B1 (about buffer

+ * required for OFDM because any phase difference adds up in the frequency
+ * domain.
+ *
+ * MRC requires extra work for use with CCK. You need to align the antenna
+ * signals from the different antenna before you can add the signals together.
+ * You need aligment of signals as CCK is in time domain, so addition can cancel
+ * your signal completely if phase is 180 degrees (think of adding sine waves).
+ * You also need to remove noise before the addition and this is where ANI
+ * MRC CCK comes into play. One of the antenna inputs may be stronger but
+ * lower SNR, so just adding after alignment can be dangerous.
+ *
+ * Regardless of alignment in time, the antenna signals add constructively after
+ * FFT and improve your reception. For more information:

+ * ath9k_hw_updatetxtriglevel - adjusts the frame trigger level

+ * @ah: atheros hardware struct
+ * @bIncTrigLevel: whether or not the frame trigger level should be updated
+ *
+ * The frame trigger level specifies the minimum number of bytes,
+ * in units of 64 bytes, that must be DMA'ed into the PCU TX FIFO
+ * before the PCU will initiate sending the frame on the air. This can
+ * mean we initiate transmit before a full frame is on the PCU TX FIFO.
+ * Resets to 0x1 (meaning 64 bytes or a full frame, whichever occurs
+ * first)
+ *
+ * Caution must be taken to ensure to set the frame trigger level based
+ * on the DMA request size. For example if the DMA request size is set to
+ * 128 bytes the trigger level cannot exceed 6 * 64 = 384. This is because
+ * there need to be enough space in the tx FIFO for the requested transfer
+ * size. Hence the tx FIFO will stop with 512 - 128 = 384 bytes. If we set
+ * the threshold to a value beyond 6, then the transmit will hang.
+ *
+ * Current dual   stream devices have a PCU TX FIFO size of 8 KB.
+ * Current single stream devices have a PCU TX FIFO size of 4 KB, however,
+ * there is a hardware issue which forces us to use 2 KB instead so the
+ * frame trigger level must not exceed 2 KB for these chipsets.

+ * ath_hw_set_bssid_mask - filter out bssids we listen
+ *
+ * @common: the ath_common struct for the device.
+ *
+ * BSSID masking is a method used by AR5212 and newer hardware to inform PCU
+ * which bits of the interface's MAC address should be looked at when trying
+ * to decide which packets to ACK. In station mode and AP mode with a single
+ * BSS every bit matters since we lock to only one BSS. In AP mode with
+ * multiple BSSes (virtual interfaces) not every bit matters because hw must
+ * accept frames for all BSSes and so we tweak some bits of our mac address
+ * in order to have multiple BSSes.
+ *
+ * NOTE: This is a simple filter and does *not* filter out all
+ * relevant frames. Some frames that are not for us might get ACKed from us
+ * by PCU because they just match the mask.
+ *
+ * When handling multiple BSSes you can get the BSSID mask by computing the
+ * set of  ~ ( MAC XOR BSSID ) for all bssids we handle.
+ *
+ * When you do this you are essentially computing the common bits of all your
+ * BSSes. Later it is assumed the hardware will "and" (&) the BSSID mask with
+ * the MAC address to obtain the relevant bits and compare the result with
+ * (frame's BSSID & mask) to see if they match.
+ *
+ * Simple example: on your card you have have two BSSes you have created with
+ * BSSID-01 and BSSID-02. Lets assume BSSID-01 will not use the MAC address.
+ * There is another BSSID-03 but you are not part of it. For simplicity's sake,
+ * assuming only 4 bits for a mac address and for BSSIDs you can then have:
+ *
+ *                  \
+ * MAC:        0001 |
+ * BSSID-01:   0100 | --> Belongs to us
+ * BSSID-02:   1001 |
+ *                  /
+ * -------------------
+ * BSSID-03:   0110  | --> External
+ * -------------------
+ *
+ * Our bssid_mask would then be:
+ *
+ *             On loop iteration for BSSID-01:
+ *             ~(0001 ^ 0100)  -> ~(0101)
+ *                             ->   1010
+ *             bssid_mask      =    1010
+ *
+ *             On loop iteration for BSSID-02:
+ *             bssid_mask &= ~(0001   ^   1001)
+ *             bssid_mask =   (1010)  & ~(0001 ^ 1001)
+ *             bssid_mask =   (1010)  & ~(1000)
+ *             bssid_mask =   (1010)  &  (0111)
+ *             bssid_mask =   0010
+ *
+ * A bssid_mask of 0010 means "only pay attention to the second least
+ * significant bit". This is because its the only bit common
+ * amongst the MAC and all BSSIDs we support. To findout what the real
+ * common bit is we can simply "&" the bssid_mask now with any BSSID we have
+ * or our MAC address (we assume the hardware uses the MAC address).
+ *
+ * Now, suppose there's an incoming frame for BSSID-03:
+ *
+ * IFRAME-01:  0110
+ *
+ * An easy eye-inspeciton of this already should tell you that this frame
+ * will not pass our check. This is because the bssid_mask tells the
+ * hardware to only look at the second least significant bit and the
+ * common bit amongst the MAC and BSSIDs is 0, this frame has the 2nd LSB
+ * as 1, which does not match 0.
+ *
+ * So with IFRAME-01 we *assume* the hardware will do:
+ *
+ *     allow = (IFRAME-01 & bssid_mask) == (bssid_mask & MAC) ? 1 : 0;
+ *  --> allow = (0110 & 0010) == (0010 & 0001) ? 1 : 0;
+ *  --> allow = (0010) == 0000 ? 1 : 0;
+ *  --> allow = 0
+ *
+ *  Lets now test a frame that should work:
+ *
+ * IFRAME-02:  0001 (we should allow)
+ *
+ *     allow = (IFRAME-02 & bssid_mask) == (bssid_mask & MAC) ? 1 : 0;
+ *  --> allow = (0001 & 0010) ==  (0010 & 0001) ? 1 :0;
+ *  --> allow = (0000) == (0000)
+ *  --> allow = 1
+ *
+ * Other examples:
+ *
+ * IFRAME-03:  0100 --> allowed
+ * IFRAME-04:  1001 --> allowed
+ * IFRAME-05:  1101 --> allowed but its not for us!!!

+  ChangeLog:
+
+  Thu Dec 6 22:40:00 1996  Markus Gutschke  <gutschk@math.uni-muenster.de>
+
+  * disabled all "advanced" features; this should make the code more reliable
+
+  * reorganized the reset function
+
+  * always reset the address port, so that autoprobing will continue working
+
+  * some cosmetic changes
+
+  * 2.5
+
+  Thu Dec 5 21:00:00 1996  Markus Gutschke  <gutschk@math.uni-muenster.de>
+
+  * tested the code against a CS8900 card
+
+  * lots of minor bug fixes and adjustments
+
+  * this is the first release, that actually works! it still requires some
+    changes in order to be more tolerant to different environments
+
+  * 4
+
+  Fri Nov 22 23:00:00 1996  Markus Gutschke  <gutschk@math.uni-muenster.de>
+
+  * read the manuals for the CS89x0 chipsets and took note of all the
+    changes that will be necessary in order to adapt Russel Nelson's code
+    to the requirements of a BOOT-Prom
+
+  * 6
+
+  Thu Nov 19 22:00:00 1996  Markus Gutschke  <gutschk@math.uni-muenster.de>
+
+  * Synched with Russel Nelson's current code (v1.00)
+
+  * 2
+
+  Thu Nov 12 18:00:00 1996  Markus Gutschke  <gutschk@math.uni-muenster.de>
+
+  * Cleaned up some of the code and tried to optimize the code size.
+
+  * 1.5
+
+  Sun Nov 10 16:30:00 1996  Markus Gutschke  <gutschk@math.uni-muenster.de>
+
+  * First experimental release. This code compiles fine, but I
+  have no way of testing whether it actually works.
+
+  * I did not (yet) bother to make the code 16bit aware, so for
+  the time being, it will only work for Etherboot/32.

+  * 12

+
+    The  driver has been tested on DE100, DE200 and DE202 cards  in  a
+    relatively busy network. The DE422 has been tested a little.
+
+    This  driver will NOT work   for the DE203,  DE204  and DE205 series  of
+    cards,  since they have  a  new custom ASIC in   place of the AMD  LANCE
+    chip.  See the 'ewrk3.c'   driver in the  Linux  source tree for running
+    those cards.
+
+    I have benchmarked the driver with a  DE100 at 595kB/s to (542kB/s from)
+    a DECstation 5000/200.

+    
+
+    Peter Bauer's depca.c (V0.5) was referred to when debugging V0.1 of this
+    driver.
+
+    The original DEPCA  card requires that the  ethernet ROM address counter
+    be enabled to count and has an 8 bit NICSR.  The ROM counter enabling is
+    only  done when a  0x08 is read as the  first address octet (to minimise
+    the chances  of writing over some  other hardware's  I/O register).  The
+    NICSR accesses   have been changed  to  byte accesses  for all the cards
+    supported by this driver, since there is only one  useful bit in the MSB
+    (remote boot timeout) and it  is not used.  Also, there  is a maximum of
+    only 48kB network  RAM for this  card.  My thanks  to Torbjorn Lindh for
+    help debugging all this (and holding my feet to  the fire until I got it
+    right).
+
+    The DE200  series  boards have  on-board 64kB  RAM for  use  as a shared
+    memory network  buffer. Only the DE100  cards make use  of a  2kB buffer
+    mode which has not  been implemented in  this driver (only the 32kB  and
+    64kB modes are supported [16kB/48kB for the original DEPCA]).
+
+    At the most only 2 DEPCA cards can  be supported on  the ISA bus because
+    there is only provision  for two I/O base addresses  on each card (0x300
+    and 0x200). The I/O address is detected by searching for a byte sequence
+    in the Ethernet station address PROM at the expected I/O address for the
+    Ethernet  PROM.   The shared memory  base   address  is 'autoprobed'  by
+    looking  for the self  test PROM  and detecting the  card name.   When a
+    second  DEPCA is  detected,  information  is   placed in the   base_addr
+    variable of the  next device structure (which  is created if necessary),
+    thus  enabling ethif_probe  initialization  for the device.  More than 2
+    EISA cards can  be  supported, but  care will  be  needed assigning  the
+    shared memory to ensure that each slot has the  correct IRQ, I/O address
+    and shared memory address assigned.
+
+    ************************************************************************
+
+    NOTE: If you are using two  ISA DEPCAs, it is  important that you assign
+    the base memory addresses correctly.   The  driver autoprobes I/O  0x300
+    then 0x200.  The  base memory address for  the first device must be less
+    than that of the second so that the auto probe will correctly assign the
+    I/O and memory addresses on the same card.  I can't think of a way to do
+    this unambiguously at the moment, since there is nothing on the cards to
+    tie I/O and memory information together.
+
+    I am unable  to  test  2 cards   together for now,    so this  code   is
+    unchecked. All reports, good or bad, are welcome.
+
+    ************************************************************************
+
+    The board IRQ   setting must be  at an  unused IRQ which  is auto-probed
+    using Donald Becker's autoprobe routines. DEPCA and DE100 board IRQs are
+    {2,3,4,5,7}, whereas the  DE200 is at {5,9,10,11,15}.  Note that IRQ2 is
+    really IRQ9 in machines with 16 IRQ lines.
+
+    No 16MB memory  limitation should exist with this  driver as DMA is  not
+    used and the common memory area is in low memory on the network card (my
+    current system has 20MB and I've not had problems yet).
+
+    The ability to load this driver as a loadable module has been added. To
+    utilise this ability, you have to do <8 things:
+
+    0) have a copy of the loadable modules code installed on your system.
+    1) copy depca.c from the  /linux/drivers/net directory to your favourite
+    temporary directory.
+    2) if you wish, edit the  source code near  line 1530 to reflect the I/O
+    address and IRQ you're using (see also 5).
+    3) compile  depca.c, but include -DMODULE in  the command line to ensure
+    that the correct bits are compiled (see end of source code).
+    4) if you are wanting to add a new  card, goto 5. Otherwise, recompile a
+    kernel with the depca configuration turned off and reboot.
+    5) insmod depca.o [irq=7] [io=0x200] [mem=0xd0000] [adapter_name=DE100]

+                                                                assignments]
+    6) run the net startup bits for your eth?? interface manually 
+    (usually /etc/rc.inet[12] at boot time). 
+    7) enjoy!
+
+    Note that autoprobing is not allowed in loadable modules - the system is
+    already up and running and you're messing with interrupts.
+
+    To unload a module, turn off the associated interface 
+    'ifconfig eth?? down' then 'rmmod depca'.
+
+    To assign a base memory address for the shared memory  when running as a
+    loadable module, see 5 above.  To include the adapter  name (if you have
+    no PROM  but know the card name)  also see 5  above. Note that this last
+    option  will not work  with kernel  built-in  depca's. 
+
+    The shared memory assignment for a loadable module  makes sense to avoid
+    the 'memory autoprobe' picking the wrong shared memory  (for the case of
+    2 depca's in a PC).
+
+    ************************************************************************
+    Support for MCA EtherWORKS cards added 11-3-98.
+    Verified to work with up to 2 DE212 cards in a system (although not
+      fully stress-tested).  
+
+    Currently known bugs/limitations:
+
+    Note:  with the MCA stuff as a module, it trusts the MCA configuration,
+           not the command line for IRQ and memory address.  You can
+           specify them if you want, but it will throw your values out.
+           You still have to pass the IO address it was configured as
+           though.

+/**************************************************************************
+Etherboot -  BOOTP/TFTP Bootstrap Program
+Intel EEPRO/10 NIC driver for Etherboot
+Adapted from Linux eepro.c from kernel 2.2.17
+
+This board accepts a 32 pin EEPROM (29C256), however a test with a
+27C010 shows that this EPROM also works in the socket, but it's not clear
+how repeatably. The two top address pins appear to be held low, thus
+the bottom 32kB of the 27C010 is visible in the CPU's address space.
+To be sure you could put 4 copies of the code in the 27C010, then
+it doesn't matter whether the extra lines are held low or high, just
+hopefully not floating as CMOS chips don't like floating inputs.
+
+Be careful with seating the EPROM as the socket on my board actually
+has 34 pins, the top row of 2 are not used.

+/*
+ * General Theory of Operation
+ *
+ * Initialization
+ *
+ * ifec_pci_probe() is called by iPXE during initialization. Typical NIC
+ * initialization is performed.  EEPROM data is read.
+ *
+ * Network Boot
+ *
+ * ifec_net_open() is called by iPXE before attempting to network boot from the
+ * card.  Here, the Command Unit & Receive Unit are initialized.  The tx & rx
+ * rings are setup.  The MAC address is programmed and the card is configured.
+ *
+ * Transmit
+ *
+ * ifec_net_transmit() enqueues a packet in the tx ring - active::tcbs[]  The tx
+ * ring is composed of TCBs linked to each other into a ring.  A tx request
+ * fills out the next available TCB with a pointer to the packet data.
+ * The last enqueued tx is always at active::tcb_head.  Thus, a tx request fills
+ * out the TCB following tcb_head.
+ * active::tcb_tail points to the TCB we're awaiting completion of.
+ * ifec_tx_process() checks tcb_tail, and once complete,
+ * blindly increments tcb_tail to the next ring TCB.
+ *
+ * Receive
+ *
+ * priv::rfds[] is an array of Receive Frame Descriptors. The RFDs are linked
+ * together to form a ring.
+ * ifec_net_poll() calls ifec_rx_process(), which checks the next RFD for
+ * data.  If we received a packet, we allocate a new io_buffer and copy the
+ * packet data into it. If alloc_iob() fails, we don't touch the RFD and try
+ * again on the next poll.
+ */
+
+/*
+ * Debugging levels:
+ *	- DBG() is for any errors, i.e. failed alloc_iob(), malloc_dma(),
+ *	  TX overflow, corrupted packets, ...
+ *	- DBG2() is for successful events, like packet received,
+ *	  packet transmitted, and other general notifications.
+ *	- DBGP() prints the name of each called function on entry

+/** @file
+ *
+ * Etherfabric bitfield access
+ *
+ * Etherfabric NICs make extensive use of bitfields up to 128 bits
+ * wide.  Since there is no native 128-bit datatype on most systems,
+ * and since 64-bit datatypes are inefficient on 32-bit systems and
+ * vice versa, we wrap accesses in a way that uses the most efficient
+ * datatype.
+ *
+ * The NICs are PCI devices and therefore little-endian.  Since most
+ * of the quantities that we deal with are DMAed to/from host memory,
+ * we define our datatypes (efab_oword_t, efab_qword_t and
+ * efab_dword_t) to be little-endian.
+ *
+ * In the less common case of using PIO for individual register
+ * writes, we construct the little-endian datatype in host memory and
+ * then use non-swapping equivalents of writel/writeq, rather than
+ * constructing a native-endian datatype and relying on the implicit
+ * byte-swapping done by writel/writeq.  (We use a similar strategy
+ * for register reads.)

+/* MAC internal memory addresses are 23 bit quantities.  The MAC uses
+ * a paged address space where the upper 16 bits are the page number
+ * and the lower 7 bits are the offset.  There are various Host API
+ * elements that require two 16-bit quantities to specify a MAC
+ * internal memory address.  Unfortunately, some of the API's use a
+ * page/offset format where the offset value is JUST the lower seven
+ * bits and the page is  the remaining 16 bits.  Some of the API's
+ * assume that the 23 bit address has been split at the 16th bit.  We
+ * refer to these two formats as AUX format and CMD format.  The
+ * macros below help handle some of this.

+ * General Theory of Operation
+ *
+ * This is a minimal Myricom 10 gigabit Ethernet driver for network
+ * boot.
+ *
+ * Initialization
+ *
+ * myri10ge_pci_probe() is called by iPXE during initialization.
+ * Minimal NIC initialization is performed to minimize resources
+ * consumed when the driver is resident but unused.
+ *
+ * Network Boot
+ *
+ * myri10ge_net_open() is called by iPXE before attempting to network
+ * boot from the card.  Packet buffers are allocated and the NIC
+ * interface is initialized.
+ *
+ * Transmit
+ *
+ * myri10ge_net_transmit() enqueues frames for transmission by writing
+ * discriptors to the NIC's tx ring.  For simplicity and to avoid
+ * copies, we always have the NIC DMA up the packet.  The sent I/O
+ * buffer is released once the NIC signals myri10ge_interrupt_handler()
+ * that the send has completed.
+ *
+ * Receive
+ *
+ * Receives are posted to the NIC's receive ring.  The NIC fills a
+ * DMAable receive_completion ring with completion notifications.
+ * myri10ge_net_poll() polls for these receive notifications, posts
+ * replacement receive buffers to the NIC, and passes received frames
+ * to netdev_rx().
+ *
+ * NonVolatile Storage
+ *
+ * This driver supports NonVolatile Storage (nvs) in the NIC EEPROM.
+ * If the last EEPROM block is not otherwise filled, we tell
+ * iPXE it may store NonVolatile Options (nvo) there.
+ */
+
+/*
+ * Debugging levels:
+ *	- DBG() is for any errors, i.e. failed alloc_iob(), malloc_dma(),
+ *	  TX overflow, corrupted packets, ...
+ *	- DBG2() is for successful events, like packet received,
+ *	  packet transmitted, and other general notifications.
+ *	- DBGP() prints the name of each called function on entry

+ *****************************************************************************/
+
+/* CRB Root Command
+
+   A single set of crbs is used across all physical/virtual
+   functions for capability queries, initialization, and
+   context creation/destruction. 
+
+   There are 4 CRBS:
+       Command/Response CRB
+       Argument1 CRB
+       Argument2 CRB
+       Argument3 CRB
+       Signature CRB 
+
+       The cmd/rsp crb is always intiated by the host via
+       a command code and always responded by the card with
+       a response code. The cmd and rsp codes are disjoint.
+       The sequence of use is always CMD, RSP, CLEAR CMD.
+
+       The arguments are for passing in command specific
+       and response specific parameters/data. 
+
+       The signature is composed of a magic value, the
+       pci function id, and a command sequence id:
+          [7:0]  = pci function
+         [15:8]  = version
+         [31:16] = magic of 0xcafe
+
+       The pci function allows the card to take correct
+       action for the given particular commands. 
+       The firmware will attempt to detect
+       an errant driver that has died while holding  
+       the root crb hardware lock. Such an error condition
+       shows up as the cmd/rsp crb stuck in a non-clear state.
+
+   Interface Sequence:
+     Host always makes requests and firmware always responds.
+     Note that data field is always set prior to command field.
+

+ * are accessed by writing a number into the BANK_SELECT register
+ * ( I also use a SMC_SELECT_BANK macro for this ).
+ *
+ * The banks are configured so that for most purposes, bank 2 is all

+ * the same mode, they may not be configured individually.
+ *
+ * This driver always uses host memory TX descriptors.
+ *
+ * To use host memory TX descriptors:
+ *	1) Set GRC_MODE_HOST_SENDBDS in GRC_MODE register.
+ *	   Make sure GRC_MODE_4X_NIC_SEND_RINGS is clear.
+ *	2) Allocate DMA'able memory.
+ *	3) In NIC_SRAM_SEND_RCB (of desired index) of on-chip SRAM:
+ *	   a) Set TG3_BDINFO_HOST_ADDR to DMA address of memory
+ *	      obtained in step 2
+ *	   b) Set TG3_BDINFO_NIC_ADDR to NIC_SRAM_TX_BUFFER_DESC.
+ *	   c) Set len field of TG3_BDINFO_MAXLEN_FLAGS to number
+ *            of TX descriptors.  Leave flags field clear.
+ *	4) Access TX descriptors via host memory.  The chip
+ *	   will refetch into local SRAM as needed when producer
+ *	   index mailboxes are updated.
+ *
+ * To use on-chip TX descriptors:
+ *	1) Set GRC_MODE_4X_NIC_SEND_RINGS in GRC_MODE register.
+ *	   Make sure GRC_MODE_HOST_SENDBDS is clear.
+ *	2) In NIC_SRAM_SEND_RCB (of desired index) of on-chip SRAM:
+ *	   a) Set TG3_BDINFO_HOST_ADDR to zero.
+ *	   b) Set TG3_BDINFO_NIC_ADDR to NIC_SRAM_TX_BUFFER_DESC
+ *	   c) TG3_BDINFO_MAXLEN_FLAGS is don't care.
+ *	3) Access TX descriptors directly in on-chip SRAM
+ *	   using normal {read,write}l().  (and not using
+ *         pointer dereferencing of ioremap()'d memory like
+ *	   the broken Broadcom driver does)
+ *
+ * Note that BDINFO_FLAGS_DISABLED should be set in the flags field of
+ * TG3_BDINFO_MAXLEN_FLAGS of all unused SEND_RCB indices.

+
+  As of April 2001 this driver should support most tulip cards that 
+  the Linux tulip driver supports because Donald Becker's Linux media 
+  detection code is now included.
+
+  Based on Ken Yap's Tulip Etherboot Driver and Donald Becker's
+  Linux Tulip Driver. Supports N-Way speed auto-configuration on
+  MX98715, MX98715A and MX98725. Support inexpensive PCI 10/100 cards
+  based on the Macronix MX987x5 chip, such as the SOHOware Fast
+  model SFA110A, and the LinkSYS model LNE100TX. The NetGear
+  model FA310X, based on the LC82C168 chip is supported.
+  The TRENDnet TE100-PCIA NIC which uses a genuine Intel 21143-PD
+  chipset is supported. Also, Davicom DM9102's.

+  08 Feb 2005  Ramesh Chander chhabaramesh at yahoo.co.in added table entries
+               for SGThomson STE10/100A
+  07 Sep 2003  timlegge	Multicast Support Added
+  11 Apr 2001  mdc     [patch to etherboot 4.7.24]
+     Major rewrite to include Linux tulip driver media detection
+     code.  This driver should support a lot more cards now.
+  16 Jul 2000  mdc     0.75b11
+     Added support for ADMtek 0985 Centaur-P, a "Comet" tulip clone
+     which is used on the LinkSYS LNE100TX v4.x cards.  We already
+     support LNE100TX v2.0 cards, which use a different controller.
+  04 Jul 2000   jam     ?
+     Added test of status after receiving a packet from the card.
+     Also uncommented the tulip_disable routine.  Stray packets
+     seemed to be causing problems.
+  27 Apr 2000   njl     ?
+  29 Feb 2000   mdc     0.75b7
+     Increased reset delay to 3 seconds because Macronix cards seem to
+     need more reset time before card comes back to a usable state.
+  26 Feb 2000   mdc     0.75b6
+     Added a 1 second delay after initializing the transmitter because
+     some cards seem to need the time or they drop the first packet 
+     transmitted.
+  23 Feb 2000   mdc     0.75b5
+     removed udelay code and used currticks() for more reliable delay
+     code in reset pause and sanity timeouts.  Added function prototypes
+     and TX debugging code.
+  21 Feb 2000   mdc     patch to Etherboot 4.4.3
+     Incorporated patches from Bob Edwards and Paul Mackerras of 
+     Linuxcare's OZLabs to deal with inefficiencies in tulip_transmit
+     and udelay.  We now wait for packet transmission to complete
+     (or sanity timeout).
+  04 Feb 2000   Robert.Edwards@anu.edu.au patch to Etherboot 4.4.2
+     patch to tulip.c that implements the automatic selection of the MII
+     interface on cards using the Intel/DEC 21143 reference design, in
+     particular, the TRENDnet TE100-PCIA NIC which uses a genuine Intel
+     21143-PD chipset.
+  11 Jan 2000   mdc     0.75b4
+     Added support for NetGear FA310TX card based on the LC82C168
+     chip.  This should also support Lite-On LC82C168 boards.
+     Added simple MII support. Re-arranged code to better modularize
+     initializations.
+  04 Dec 1999   mdc     0.75b3
+     Added preliminary support for LNE100TX PCI cards.  Should work for
+     PNIC2 cards. No MII support, but single interface (RJ45) tulip
+     cards seem to not care.
+  03 Dec 1999   mdc     0.75b2
+     Renamed from mx987x5 to tulip, merged in original tulip init code
+     from tulip.c to support other tulip compatible cards.
+  02 Dec 1999   mdc     0.75b1
+     Released Beta MX987x5 Driver for code review and testing to netboot
+     and thinguin mailing lists.

+
+This is a tulip and clone driver for Etherboot.  See the revision
+history in the tulip.c file for information on changes.  This version
+of the driver incorporates changes from Bob Edwards and Paul Mackerras
+who cantributed changes to support the TRENDnet TE100-PCIA NIC which
+uses a genuine Intel 21143-PD chipset.  There are also various code
+cleanups to make time-based activities more reliable.
+
+Of course you have to have all the usual Etherboot environment
+(bootp/dhcp/NFS) set up, and you need a Linux kernel with v0.91g
+(7.16.99) or later of the tulip.c driver compiled in to support some
+MX98715 based cards.  That file is available at:
+
+  http://cesdis.gsfc.nasa.gov/linux/drivers/test/tulip.c
+
+NOTES
+
+I've tested this driver with a SOHOware Fast 10/100 Model SDA110A,
+a Linksys LNE100TX v2.0, and a Netgear FA310TX card, and it worked at
+both 10 and 100 mbits. Other cards based on the tulip family may work as
+well.
+
+These cards are about 20$US, are supported by Linux and now Etherboot,
+and being PCI, they auto-configure IRQ and IOADDR and auto-negotiate
+10/100 half/full duplex. It seems like a pretty good value compared to
+some of the pricier cards, and can lower the cost of building/adapting
+thin client workstations substantially while giving a considerable
+performance increase.
+
+On some PCI tulip clone chipsets (MX987x5, LC82C115, LC82C168) this driver 
+lets the card choose the fastest speed it can negotiate with the peer
+device.  On other cards, it chooses 10mbit half-duplex.
+
+I burned an AM27C256 (32KByte) EPROM with mx987x5.lzrom and it worked.
+According to the data sheet the MX98715A supports up to 64K (27C512)
+EPROMs, 
+
+I've liberally commented the code and header files in the hope that it
+will help the next person who hacks the code or needs to support some
+tulip clone card, or wishes to add functionality.
+
+Anyway, please test this if you can on your tulip based card, and let
+me (mdc@etherboot.org) and the Etherboot-Discuss list
+(etherboot-discuss@lists.sourceforge.net) know how things go.  I also
+would appreciate code review by people who program.  I'm a strong
+believer in "another set of eyes".
+

+ * Virtio network device driver
+ *
+ * Specification:
+ * http://ozlabs.org/~rusty/virtio-spec/
+ *
+ * The virtio network device is supported by Linux virtualization software
+ * including QEMU/KVM and lguest.  This driver supports the virtio over PCI
+ * transport; virtual machines have one virtio-net PCI adapter per NIC.
+ *
+ * Virtio-net is different from hardware NICs because virtio devices
+ * communicate with the hypervisor via virtqueues, not traditional descriptor
+ * rings.  Virtqueues are unordered queues, they support add_buf() and
+ * get_buf() operations.  To transmit a packet, the driver has to add the
+ * packet buffer onto the virtqueue.  To receive a packet, the driver must
+ * first add an empty buffer to the virtqueue and then get the filled packet
+ * buffer on completion.
+ *
+ * Virtqueues are an abstraction that is commonly implemented using the vring
+ * descriptor ring layout.  The vring is the actual shared memory structure
+ * that allows the virtual machine to communicate buffers with the hypervisor.
+ * Because the vring layout is optimized for flexibility and performance rather
+ * than space, it is heavy-weight and allocated like traditional descriptor
+ * rings in the open() function of the driver and not in probe().
+ *
+ * There is no true interrupt enable/disable.  Virtqueues have callback
+ * enable/disable flags but these are only hints.  The hypervisor may still
+ * raise an interrupt.  Nevertheless, this driver disables callbacks in the
+ * hopes of avoiding interrupts.

+ * This is the etherboot driver for cards based on Winbond W89c840F chip.
+ *
+ * It was written from skeleton source, with Donald Becker's winbond-840.c
+ * kernel driver as a guideline. Mostly the w89c840 related definitions
+ * and the lower level routines have been cut-and-pasted into this source.
+ *
+ * Frankly speaking, about 90% of the code was obtained using cut'n'paste
+ * sequence :) while the remainder appeared while brainstorming
+ * Linux Kernel 2.4.0-testX source code. Thanks, Donald and Linus!
+ *
+ * There was a demand for using this card in a rather large
+ * remote boot environment at MSKP OVTI Lab of
+ * Moscow Institute for Physics and Technology (MIPT) -- http://www.mipt.ru/
+ * so you may count that for motivation.

+ *
+ * Error codes
+ *
+ * Return status codes as used within iPXE are designed to allow for
+ * maximum visibility into the source of an error even in an end-user
+ * build with no debugging.  They are constructed as follows:
+ *
+ * Bits 7-0 : Platform-specific error code
+ *
+ * This is a losslessly compressed representation of the closest
+ * equivalent error code defined by the platform (e.g. BIOS/PXE or
+ * EFI).  It is used to generate errors to be returned to external
+ * code.
+ *
+ * Bits 12-8 : Per-file disambiguator
+ *
+ * When the same error code can be generated from multiple points
+ * within a file, this field can be used to identify the unique
+ * instance.
+ *
+ * Bits 23-13 : File identifier
+ *
+ * This is a unique identifier for the file generating the error
+ * (e.g. ERRFILE_tcp for tcp.c).
+ *
+ * Bits 30-24 : POSIX error code
+ *
+ * This is the closest equivalent POSIX error code (e.g. ENOMEM).
+ *
+ * Bit 31 : Reserved
+ *
+ * Errors are usually return as negative error codes (e.g. -EINVAL);
+ * bit 31 is therefore unusable.
+ *
+ *
+ * The convention within the code is that errors are negative and
+ * expressed using the POSIX error, e.g.
+ *
+ *     return -EINVAL;
+ *
+ * By various bits of preprocessor magic, the platform-specific error
+ * code and file identifier are already incorporated into the
+ * definition of the POSIX error macro, which keeps the code
+ * relatively clean.
+ *
+ *
+ * Functions that wish to return failures should be declared as
+ * returning an integer @c rc "Return status code".  A return value of
+ * zero indicates success, a non-zero value indicates failure.  The
+ * return value can be passed directly to strerror() in order to
+ * generate a human-readable error message, e.g.
+ *
+ *     if ( ( rc = some_function ( ... ) ) != 0 ) {
+ *         DBG ( "Whatever I was trying to do failed: %s\n", strerror ( rc ) );
+ *         return rc;
+ *     }
+ *
+ * As illustrated in the above example, error returns should generally
+ * be directly propagated upward to the calling function.
+ *
+ *
+ * Individual files may declare localised errors using
+ * __einfo_uniqify().  For example, iscsi.c declares a localised
+ * version of EACCES for the error of "access denied due to incorrect
+ * target username":
+ *
+ *     #define EACCES_INCORRECT_TARGET_USERNAME	\
+ *         __einfo_error ( EINFO_EACCES_INCORRECT_TARGET_USERNAME )
+ *     #define EINFO_EACCES_INCORRECT_TARGET_USERNAME \
+ *         __einfo_uniqify ( EINFO_EACCESS, 0x01, "Incorrect target username" )
+ *
+ * which can then be used as:
+ *
+ *     return -EACCES_INCORRECT_TARGET_USERNAME;
+ *

+ * An ATA Logical Block Address
+ *
+ * ATA controllers have three byte-wide registers for specifying the
+ * block address: LBA Low, LBA Mid and LBA High.  This allows for a
+ * 24-bit address.  Some devices support the "48-bit address feature
+ * set" (LBA48), in which case each of these byte-wide registers is
+ * actually a two-entry FIFO, and the "previous" byte pushed into the
+ * FIFO is used as the corresponding high-order byte.  So, to set up
+ * the 48-bit address 0x123456abcdef, you would issue
+ *
+ *     0x56 -> LBA Low register
+ *     0xef -> LBA Low register
+ *     0x34 -> LBA Mid register
+ *     0xcd -> LBA Mid register
+ *     0x12 -> LBA High register
+ *     0xab -> LBA High register
+ *
+ * This structure encapsulates this information by providing a single
+ * 64-bit integer in native byte order, unioned with bytes named so
+ * that the sequence becomes
+ *
+ *     low_prev  -> LBA Low register
+ *     low_cur   -> LBA Low register
+ *     mid_prev  -> LBA Mid register
+ *     mid_cur   -> LBA Mid register
+ *     high_prev -> LBA High register
+ *     high_cur  -> LBA High register
+ *
+ * Just to complicate matters further, in non-LBA48 mode it is
+ * possible to have a 28-bit address, in which case bits 27:24 must be
+ * written into the low four bits of the Device register.

+  This function is used to insert entries into the ARP cache.

+  by the Add() function may be static (will not time out) or dynamic (will time out).
+  Default ARP cache timeout values are not covered in most network protocol
+  specifications (although RFC 1122 comes pretty close) and will only be
+  discussed in general terms in this specification. The timeout values that are
+  used in the EFI Sample Implementation should be used only as a guideline.

+  Callback routine.
+
+  EFI_DHCP4_CALLBACK is provided by the consumer of the EFI DHCPv4 Protocol driver
+  to intercept events that occurred in the configuration process. This structure
+  provides advanced control of each state transition of the DHCP process. The
+  returned status code determines the behavior of the EFI DHCPv4 Protocol driver.
+  There are three possible returned values, which are described in the following
+  table.
+
+  @param  This                  The pointer to the EFI DHCPv4 Protocol instance that is used to
+                                configure this callback function.
+  @param  Context               The pointer to the context that is initialized by
+                                EFI_DHCP4_PROTOCOL.Configure().
+  @param  CurrentState          The current operational state of the EFI DHCPv4 Protocol
+                                driver.
+  @param  Dhcp4Event            The event that occurs in the current state, which usually means a
+                                state transition.
+  @param  Packet                The DHCP packet that is going to be sent or already received.
+  @param  NewPacket             The packet that is used to replace the above Packet.
+
+  @retval EFI_SUCCESS           Tells the EFI DHCPv4 Protocol driver to continue the DHCP process.
+                                When it is in the Dhcp4Selecting state, it tells the EFI DHCPv4 Protocol
+                                driver to stop collecting additional packets. The driver will exit
+                                the Dhcp4Selecting state and enter the Dhcp4Requesting state.
+  @retval EFI_NOT_READY         Only used in the Dhcp4Selecting state. The EFI DHCPv4 Protocol
+                                driver will continue to wait for more packets until the retry
+                                timeout expires.
+  @retval EFI_ABORTED           Tells the EFI DHCPv4 Protocol driver to abort the current process and
+                                return to the Dhcp4Init or Dhcp4InitReboot state.

+  This function checks to see if the driver specified by This supports the device specified by
+  ControllerHandle. Drivers will typically use the device path attached to
+  ControllerHandle and/or the services from the bus I/O abstraction attached to
+  ControllerHandle to determine if the driver supports ControllerHandle. This function
+  may be called many times during platform initialization. In order to reduce boot times, the tests
+  performed by this function must be very small, and take as little time as possible to execute. This
+  function must not change the state of any hardware devices, and this function must be aware that the
+  device specified by ControllerHandle may already be managed by the same driver or a
+  different driver. This function must match its calls to AllocatePages() with FreePages(),
+  AllocatePool() with FreePool(), and OpenProtocol() with CloseProtocol().
+  Because ControllerHandle may have been previously started by the same driver, if a protocol is
+  already in the opened state, then it must not be closed with CloseProtocol(). This is required
+  to guarantee the state of ControllerHandle is not modified by this function.
+
+  @param[in]  This                 A pointer to the EFI_DRIVER_BINDING_PROTOCOL instance.
+  @param[in]  ControllerHandle     The handle of the controller to test. This handle
+                                   must support a protocol interface that supplies
+                                   an I/O abstraction to the driver.
+  @param[in]  RemainingDevicePath  A pointer to the remaining portion of a device path.  This
+                                   parameter is ignored by device drivers, and is optional for bus
+                                   drivers. For bus drivers, if this parameter is not NULL, then
+                                   the bus driver must determine if the bus controller specified
+                                   by ControllerHandle and the child controller specified
+                                   by RemainingDevicePath are both supported by this
+                                   bus driver.

+  This file defines the EFI IPv4 (Internet Protocol version 4)
+  Protocol interface. It is split into the following three main
+  sections:
+  - EFI IPv4 Service Binding Protocol
+  - EFI IPv4 Variable (deprecated in UEFI 2.4B)
+  - EFI IPv4 Protocol.
+  The EFI IPv4 Protocol provides basic network IPv4 packet I/O services,
+  which includes support foR a subset of the Internet Control Message
+  Protocol (ICMP) and may include support for the Internet Group Management
+  Protocol (IGMP).

+  Starts running the configuration policy for the EFI IPv4 Protocol driver.
+
+  The Start() function is called to determine and to begin the platform
+  configuration policy by the EFI IPv4 Protocol driver. This determination may
+  be as simple as returning EFI_UNSUPPORTED if there is no EFI IPv4 Protocol
+  driver configuration policy. It may be as involved as loading some defaults
+  from nonvolatile storage, downloading dynamic data from a DHCP server, and
+  checking permissions with a site policy server.
+  Starting the configuration policy is just the beginning. It may finish almost
+  instantly or it may take several minutes before it fails to retrieve configuration
+  information from one or more servers. Once the policy is started, drivers
+  should use the DoneEvent parameter to determine when the configuration policy
+  has completed. EFI_IP4_CONFIG_PROTOCOL.GetData() must then be called to
+  determine if the configuration succeeded or failed.
+  Until the configuration completes successfully, EFI IPv4 Protocol driver instances
+  that are attempting to use default configurations must return EFI_NO_MAPPING.
+  Once the configuration is complete, the EFI IPv4 Configuration Protocol driver
+  signals DoneEvent. The configuration may need to be updated in the future.
+  Note that in this case the EFI IPv4 Configuration Protocol driver must signal
+  ReconfigEvent, and all EFI IPv4 Protocol driver instances that are using default
+  configurations must return EFI_NO_MAPPING until the configuration policy has
+  been rerun.
+
+  @param  This                   The pointer to the EFI_IP4_CONFIG_PROTOCOL instance.
+  @param  DoneEvent              Event that will be signaled when the EFI IPv4

+                                 execution. This event must be of type EVT_NOTIFY_SIGNAL.
+  @param  ReconfigEvent          Event that will be signaled when the EFI IPv4
+                                 Protocol driver configuration needs to be updated.
+                                 This event must be of type EVT_NOTIFY_SIGNAL.

+  Used to perform TFTP and MTFTP services.
+
+  This function is used to perform TFTP and MTFTP services. This includes the
+  TFTP operations to get the size of a file, read a directory, read a file, and
+  write a file. It also includes the MTFTP operations to get the size of a file,
+  read a directory, and read a file. The type of operation is specified by Operation.
+  If the callback function that is invoked during the TFTP/MTFTP operation does
+  not return EFI_PXE_BASE_CODE_CALLBACK_STATUS_CONTINUE, then EFI_ABORTED will
+  be returned.
+  For read operations, the return data will be placed in the buffer specified by
+  BufferPtr. If BufferSize is too small to contain the entire downloaded file,
+  then EFI_BUFFER_TOO_SMALL will be returned and BufferSize will be set to zero
+  or the size of the requested file (the size of the requested file is only returned
+  if the TFTP server supports TFTP options). If BufferSize is large enough for the
+  read operation, then BufferSize will be set to the size of the downloaded file,
+  and EFI_SUCCESS will be returned. Applications using the PxeBc.Mtftp() services
+  should use the get-file-size operations to determine the size of the downloaded
+  file prior to using the read-file operations--especially when downloading large
+  (greater than 64 MB) files--instead of making two calls to the read-file operation.
+  Following this recommendation will save time if the file is larger than expected
+  and the TFTP server does not support TFTP option extensions. Without TFTP option
+  extension support, the client has to download the entire file, counting and discarding
+  the received packets, to determine the file size.
+  For write operations, the data to be sent is in the buffer specified by BufferPtr.
+  BufferSize specifies the number of bytes to send. If the write operation completes
+  successfully, then EFI_SUCCESS will be returned.
+  For TFTP "get file size" operations, the size of the requested file or directory
+  is returned in BufferSize, and EFI_SUCCESS will be returned. If the TFTP server
+  does not support options, the file will be downloaded into a bit bucket and the
+  length of the downloaded file will be returned. For MTFTP "get file size" operations,
+  if the MTFTP server does not support the "get file size" option, EFI_UNSUPPORTED
+  will be returned.
+  This function can take up to 10 seconds to timeout and return control to the caller.
+  If the TFTP sequence does not complete, EFI_TIMEOUT will be returned.
+  If the Callback Protocol does not return EFI_PXE_BASE_CODE_CALLBACK_STATUS_CONTINUE,
+  then the TFTP sequence is stopped and EFI_ABORTED will be returned.
+  The format of the data returned from a TFTP read directory operation is a null-terminated
+  filename followed by a null-terminated information string, of the form
+  "size year-month-day hour:minute:second" (i.e. %d %d-%d-%d %d:%d:%f - note that
+  the seconds field can be a decimal number), where the date and time are UTC. For
+  an MTFTP read directory command, there is additionally a null-terminated multicast
+  IP address preceding the filename of the form %d.%d.%d.%d for IP v4. The final
+  entry is itself null-terminated, so that the final information string is terminated
+  with two null octets.
+

+                                be overwritten.
+  @param  BufferSize            For get-file-size operations, *BufferSize returns the size of the
+                                requested file.
+  @param  BlockSize             The requested block size to be used during a TFTP transfer.

+/**
+  The function reads the next keystroke from the input device. If
+  there is no pending keystroke the function returns
+  EFI_NOT_READY. If there is a pending keystroke, then
+  KeyData.Key.ScanCode is the EFI scan code defined in Error!
+  Reference source not found. The KeyData.Key.UnicodeChar is the
+  actual printable character or is zero if the key does not
+  represent a printable character (control key, function key,
+  etc.). The KeyData.KeyState is shift state for the character
+  reflected in KeyData.Key.UnicodeChar or KeyData.Key.ScanCode .
+  When interpreting the data from this function, it should be
+  noted that if a class of printable characters that are
+  normally adjusted by shift modifiers (e.g. Shift Key + "f"
+  key) would be presented solely as a KeyData.Key.UnicodeChar
+  without the associated shift state. So in the previous example
+  of a Shift Key + "f" key being pressed, the only pertinent
+  data returned would be KeyData.Key.UnicodeChar with the value
+  of "F". This of course would not typically be the case for
+  non-printable characters such as the pressing of the Right
+  Shift Key + F10 key since the corresponding returned data
+  would be reflected both in the KeyData.KeyState.KeyShiftState
+  and KeyData.Key.ScanCode values. UEFI drivers which implement
+  the EFI_SIMPLE_TEXT_INPUT_EX protocol are required to return
+  KeyData.Key and KeyData.KeyState values. These drivers must
+  always return the most current state of
+  KeyData.KeyState.KeyShiftState and
+  KeyData.KeyState.KeyToggleState. It should also be noted that
+  certain input devices may not be able to produce shift or toggle
+  state information, and in those cases the high order bit in the
+  respective Toggle and Shift state fields should not be active.

+  Adds and deletes routing table entries.
+
+  The Routes() function adds a route to or deletes a route from the routing table.
+  Routes are determined by comparing the SubnetAddress with the destination IP
+  address and arithmetically AND-ing it with the SubnetMask. The gateway address
+  must be on the same subnet as the configured station address.
+  The default route is added with SubnetAddress and SubnetMask both set to 0.0.0.0.
+  The default route matches all destination IP addresses that do not match any
+  other routes.
+  A zero GatewayAddress is a nonroute. Packets are sent to the destination IP
+  address if it can be found in the Address Resolution Protocol (ARP) cache or
+  on the local subnet. One automatic nonroute entry will be inserted into the
+  routing table for outgoing packets that are addressed to a local subnet
+  (gateway address of 0.0.0.0).
+  Each instance of the EFI UDPv4 Protocol has its own independent routing table.
+  Instances of the EFI UDPv4 Protocol that use the default IP address will also
+  have copies of the routing table provided by the EFI_IP4_CONFIG_PROTOCOL. These
+  copies will be updated automatically whenever the IP driver reconfigures its
+  instances; as a result, the previous modification to these copies will be lost.

+ * EFI platform error codes
+ *
+ * We derive our platform error codes from the possible values for
+ * EFI_STATUS defined in the UEFI specification.
+ *
+ * EFI_STATUS codes are 32/64-bit values consisting of a top bit which
+ * is set for errors and clear for warnings, and a mildly undefined
+ * code of low bits indicating the precise error/warning code.  Errors
+ * and warnings have completely separate namespaces.
+ *
+ * We assume that no EFI_STATUS code will ever be defined which uses
+ * more than bits 0-6 of the low bits.  We then choose to encode our
+ * platform-specific error by mapping bit 31/63 of the EFI_STATUS to
+ * bit 7 of the platform-specific error code, and preserving bits 0-6
+ * as-is.

+/** @page ifdef_harmful #ifdef considered harmful
+ *
+ * Overuse of @c #ifdef has long been a problem in Etherboot.
+ * Etherboot provides a rich array of features, but all these features
+ * take up valuable space in a ROM image.  The traditional solution to
+ * this problem has been for each feature to have its own @c #ifdef
+ * option, allowing the feature to be compiled in only if desired.
+ *
+ * The problem with this is that it becomes impossible to compile, let
+ * alone test, all possible versions of Etherboot.  Code that is not
+ * typically used tends to suffer from bit-rot over time.  It becomes
+ * extremely difficult to predict which combinations of compile-time
+ * options will result in code that can even compile and link
+ * correctly.
+ *
+ * To solve this problem, we have adopted a new approach from
+ * Etherboot 5.5 onwards.  @c #ifdef is now "considered harmful", and
+ * its use should be minimised.  Separate features should be
+ * implemented in separate @c .c files, and should \b always be
+ * compiled (i.e. they should \b not be guarded with a @c #ifdef @c
+ * MY_PET_FEATURE statement).  By making (almost) all code always
+ * compile, we avoid the problem of bit-rot in rarely-used code.
+ *
+ * The file config.h, in combination with the @c make command line,
+ * specifies the objects that will be included in any particular build
+ * of Etherboot.  For example, suppose that config.h includes the line
+ *
+ * @code
+ *
+ *   #define CONSOLE_SERIAL
+ *   #define DOWNLOAD_PROTO_TFTP
+ *
+ * @endcode
+ *
+ * When a particular Etherboot image (e.g. @c bin/rtl8139.zdsk) is
+ * built, the options specified in config.h are used to drag in the
+ * relevant objects at link-time.  For the above example, serial.o and
+ * tftp.o would be linked in.
+ *
+ * There remains one problem to solve: how do these objects get used?
+ * Traditionally, we had code such as
+ *
+ * @code
+ *
+ *    #ifdef CONSOLE_SERIAL
+ *      serial_init();
+ *    #endif
+ *
+ * @endcode
+ *
+ * in main.c, but this reintroduces @c #ifdef and so is a Bad Idea.
+ * We cannot simply remove the @c #ifdef and make it
+ *
+ * @code
+ *
+ *   serial_init();
+ *
+ * @endcode
+ *
+ * because then serial.o would end up always being linked in.
+ *
+ * The solution is to use @link tables.h linker tables @endlink.
+ *
+ */
+
+/** @file
+ *
+ * Linker tables
+ *
+ * Read @ref ifdef_harmful first for some background on the motivation
+ * for using linker tables.
+ *
+ * This file provides macros for dealing with linker-generated tables
+ * of fixed-size symbols.  We make fairly extensive use of these in
+ * order to avoid @c #ifdef spaghetti and/or linker symbol pollution.
+ * For example, instead of having code such as
+ *
+ * @code
+ *
+ *    #ifdef CONSOLE_SERIAL
+ *      serial_init();
+ *    #endif
+ *
+ * @endcode
+ *
+ * we make serial.c generate an entry in the initialisation function
+ * table, and then have a function call_init_fns() that simply calls
+ * all functions present in this table.  If and only if serial.o gets
+ * linked in, then its initialisation function will be called.  We
+ * avoid linker symbol pollution (i.e. always dragging in serial.o
+ * just because of a call to serial_init()) and we also avoid @c
+ * #ifdef spaghetti (having to conditionalise every reference to
+ * functions in serial.c).
+ *
+ * The linker script takes care of assembling the tables for us.  All
+ * our table sections have names of the format @c .tbl.NAME.NN where
+ * @c NAME designates the data structure stored in the table (e.g. @c
+ * init_fns) and @c NN is a two-digit decimal number used to impose an
+ * ordering upon the tables if required.  @c NN=00 is reserved for the
+ * symbol indicating "table start", and @c NN=99 is reserved for the
+ * symbol indicating "table end".
+ *
+ * As an example, suppose that we want to create a "frobnicator"
+ * feature framework, and allow for several independent modules to
+ * provide frobnicating services.  Then we would create a frob.h
+ * header file containing e.g.
+ *
+ * @code
+ *
+ *   struct frobnicator {
+ *      const char *name;		// Name of the frobnicator
+ *	void ( *frob ) ( void ); 	// The frobnicating function itself
+ *   };
+ *
+ *   #define FROBNICATORS __table ( struct frobnicator, "frobnicators" )
+ *
+ *   #define __frobnicator __table_entry ( FROBNICATORS, 01 )
+ *
+ * @endcode
+ *
+ * Any module providing frobnicating services would look something
+ * like
+ *
+ * @code
+ *
+ *   #include "frob.h"
+ *
+ *   static void my_frob ( void ) {
+ *	// Do my frobnicating
+ *	...
+ *   }
+ *
+ *   struct frob my_frobnicator __frobnicator = {
+ *	.name = "my_frob",
+ *	.frob = my_frob,
+ *   };
+ *
+ * @endcode
+ *
+ * The central frobnicator code (frob.c) would use the frobnicating
+ * modules as follows
+ *
+ * @code
+ *
+ *   #include "frob.h"
+ *
+ *   // Call all linked-in frobnicators
+ *   void frob_all ( void ) {
+ *	struct frob *frob;

+/* The following defines the magic code sequences which the JITter
+   spots and handles magically.  Don't look too closely at them as
+   they will rot your brain.
+
+   The assembly code sequences for all architectures is in this one
+   file.  This is because this file must be stand-alone, and we don't
+   want to have multiple files.
+
+   For VALGRIND_DO_CLIENT_REQUEST, we must ensure that the default
+   value gets put in the return slot, so that everything works when
+   this is executed not under Valgrind.  Args are passed in a memory
+   block, and so there's no intrinsic limit to the number that could
+   be passed, but it's currently five.
+   
+   The macro args are: 
+      _zzq_rlval    result lvalue
+      _zzq_default  default value (result returned when running on real CPU)
+      _zzq_request  request code
+      _zzq_arg1..5  request params
+
+   The other two macros are used to support function wrapping, and are
+   a lot simpler.  VALGRIND_GET_NR_CONTEXT returns the value of the
+   guest's NRADDR pseudo-register and whatever other information is
+   needed to safely run the call original from the wrapper: on
+   ppc64-linux, the R2 value at the divert point is also needed.  This
+   information is abstracted into a user-visible type, OrigFn.
+
+   VALGRIND_CALL_NOREDIR_* behaves the same as the following on the
+   guest, but guarantees that the branch instruction will not be
+   redirected: x86: call *%eax, amd64: call *%rax, ppc32/ppc64:
+   branch-and-link-to-r11.  VALGRIND_CALL_NOREDIR is just text, not a
+   complete inline asm, since it needs to be combined with more magic
+   inline asm stuff to be useful.

+/* NB 9 Sept 07.  There is a nasty kludge here in all these CALL_FN_
+   macros.  In order not to trash the stack redzone, we need to drop
+   %rsp by 128 before the hidden call, and restore afterwards.  The
+   nastyness is that it is only by luck that the stack still appears
+   to be unwindable during the hidden call - since then the behaviour
+   of any routine using this macro does not match what the CFI data
+   says.  Sigh.
+
+   Why is this important?  Imagine that a wrapper has a stack
+   allocated local, and passes to the hidden call, a pointer to it.
+   Because gcc does not know about the hidden call, it may allocate
+   that local in the redzone.  Unfortunately the hidden call may then
+   trash it before it comes to use it.  So we must step clear of the
+   redzone, for the duration of the hidden call, to make it safe.
+
+   Probably the same problem afflicts the other redzone-style ABIs too
+   (ppc64-linux, ppc32-aix5, ppc64-aix5); but for those, the stack is
+   self describing (none of this CFI nonsense) so at least messing
+   with the stack pointer doesn't give a danger of non-unwindable
+   stack. */

+/* Several Valgrind tools (Memcheck, Massif, Helgrind, DRD) rely on knowing
+   when heap blocks are allocated in order to give accurate results.  This
+   happens automatically for the standard allocator functions such as
+   malloc(), calloc(), realloc(), memalign(), new, new[], free(), delete,
+   delete[], etc.
+
+   But if your program uses a custom allocator, this doesn't automatically
+   happen, and Valgrind will not do as well.  For example, if you allocate
+   superblocks with mmap() and then allocates chunks of the superblocks, all
+   Valgrind's observations will be at the mmap() level and it won't know that
+   the chunks should be considered separate entities.  In Memcheck's case,
+   that means you probably won't get heap block overrun detection (because
+   there won't be redzones marked as unaddressable) and you definitely won't
+   get any leak detection.
+
+   The following client requests allow a custom allocator to be annotated so
+   that it can be handled accurately by Valgrind.
+
+   VALGRIND_MALLOCLIKE_BLOCK marks a region of memory as having been allocated
+   by a malloc()-like function.  For Memcheck (an illustrative case), this
+   does two things:
+
+   - It records that the block has been allocated.  This means any addresses
+     within the block mentioned in error messages will be
+     identified as belonging to the block.  It also means that if the block
+     isn't freed it will be detected by the leak checker.
+
+   - It marks the block as being addressable and undefined (if 'is_zeroed' is
+     not set), or addressable and defined (if 'is_zeroed' is set).  This
+     controls how accesses to the block by the program are handled.
+   
+   'addr' is the start of the usable block (ie. after any
+   redzone), 'sizeB' is its size.  'rzB' is the redzone size if the allocator
+   can apply redzones -- these are blocks of padding at the start and end of
+   each block.  Adding redzones is recommended as it makes it much more likely
+   Valgrind will spot block overruns.  `is_zeroed' indicates if the memory is
+   zeroed (or filled with another predictable value), as is the case for
+   calloc().
+   
+   VALGRIND_MALLOCLIKE_BLOCK should be put immediately after the point where a
+   heap block -- that will be used by the client program -- is allocated.
+   It's best to put it at the outermost level of the allocator if possible;
+   for example, if you have a function my_alloc() which calls
+   internal_alloc(), and the client request is put inside internal_alloc(),
+   stack traces relating to the heap block will contain entries for both
+   my_alloc() and internal_alloc(), which is probably not what you want.
+
+   For Memcheck users: if you use VALGRIND_MALLOCLIKE_BLOCK to carve out
+   custom blocks from within a heap block, B, that has been allocated with
+   malloc/calloc/new/etc, then block B will be *ignored* during leak-checking
+   -- the custom blocks will take precedence.
+
+   VALGRIND_FREELIKE_BLOCK is the partner to VALGRIND_MALLOCLIKE_BLOCK.  For
+   Memcheck, it does two things:
+
+   - It records that the block has been deallocated.  This assumes that the
+     block was annotated as having been allocated via
+     VALGRIND_MALLOCLIKE_BLOCK.  Otherwise, an error will be issued.
+
+   - It marks the block as being unaddressable.
+
+   VALGRIND_FREELIKE_BLOCK should be put immediately after the point where a
+   heap block is deallocated.
+
+   In many cases, these two client requests will not be enough to get your
+   allocator working well with Memcheck.  More specifically, if your allocator
+   writes to freed blocks in any way then a VALGRIND_MAKE_MEM_UNDEFINED call
+   will be necessary to mark the memory as addressable just before the zeroing
+   occurs, otherwise you'll get a lot of invalid write errors.  For example,
+   you'll need to do this if your allocator recycles freed blocks, but it
+   zeroes them before handing them back out (via VALGRIND_MALLOCLIKE_BLOCK).
+   Alternatively, if your allocator reuses freed blocks for allocator-internal
+   data structures, VALGRIND_MAKE_MEM_UNDEFINED calls will also be necessary.
+
+   Really, what's happening is a blurring of the lines between the client
+   program and the allocator... after VALGRIND_FREELIKE_BLOCK is called, the
+   memory should be considered unaddressable to the client program, but the
+   allocator knows more than the rest of the client program and so may be able
+   to safely access it.  Extra client requests are necessary for Valgrind to
+   understand the distinction between the allocator and the rest of the
+   program.
+
+   Note: there is currently no VALGRIND_REALLOCLIKE_BLOCK client request;  it
+   has to be emulated with MALLOCLIKE/FREELIKE and memory copying.

+/*
+ * `incontents 50 arm_abi Hypercall Calling Convention
+ *
+ * A hypercall is issued using the ARM HVC instruction.
+ *
+ * A hypercall can take up to 5 arguments. These are passed in
+ * registers, the first argument in x0/r0 (for arm64/arm32 guests
+ * respectively irrespective of whether the underlying hypervisor is
+ * 32- or 64-bit), the second argument in x1/r1, the third in x2/r2,
+ * the forth in x3/r3 and the fifth in x4/r4.
+ *
+ * The hypercall number is passed in r12 (arm) or x16 (arm64). In both
+ * cases the relevant ARM procedure calling convention specifies this
+ * is an inter-procedure-call scratch register (e.g. for use in linker
+ * stubs). This use does not conflict with use during a hypercall.
+ *
+ * The HVC ISS must contain a Xen specific TAG: XEN_HYPERCALL_TAG.
+ *
+ * The return value is in x0/r0.
+ *
+ * The hypercall will clobber x16/r12 and the argument registers used
+ * by that hypercall (except r0 which is the return value) i.e. in
+ * addition to x16/r12 a 2 argument hypercall will clobber x1/r1 and a
+ * 4 argument hypercall will clobber x1/r1, x2/r2 and x3/r3.
+ *
+ * Parameter structs passed to hypercalls are laid out according to
+ * the Procedure Call Standard for the ARM Architecture (AAPCS, AKA
+ * EABI) and Procedure Call Standard for the ARM 64-bit Architecture
+ * (AAPCS64). Where there is a conflict the 64-bit standard should be
+ * used regardless of guest type. Structures which are passed as
+ * hypercall arguments are always little endian.
+ *
+ * All memory which is shared with other entities in the system
+ * (including the hypervisor and other guests) must reside in memory
+ * which is mapped as Normal Inner-cacheable. This applies to:
+ *  - hypercall arguments passed via a pointer to guest memory.
+ *  - memory shared via the grant table mechanism (including PV I/O
+ *    rings etc).
+ *  - memory shared with the hypervisor (struct shared_info, struct
+ *    vcpu_info, the grant table, etc).
+ *
+ * Any Inner cache allocation strategy (Write-Back, Write-Through etc)
+ * is acceptable. There is no restriction on the Outer-cacheability.
+ */
+
+/*
+ * `incontents 55 arm_hcall Supported Hypercalls
+ *
+ * Xen on ARM makes extensive use of hardware facilities and therefore
+ * only a subset of the potential hypercalls are required.
+ *
+ * Since ARM uses second stage paging any machine/physical addresses
+ * passed to hypercalls are Guest Physical Addresses (Intermediate
+ * Physical Addresses) unless otherwise noted.
+ *
+ * The following hypercalls (and sub operations) are supported on the
+ * ARM platform. Other hypercalls should be considered
+ * unavailable/unsupported.
+ *
+ *  HYPERVISOR_memory_op
+ *   All generic sub-operations.
+ *
+ *   In addition the following arch specific sub-ops:
+ *    * XENMEM_add_to_physmap
+ *    * XENMEM_add_to_physmap_batch
+ *
+ *  HYPERVISOR_domctl
+ *   All generic sub-operations, with the exception of:
+ *    * XEN_DOMCTL_iomem_permission (not yet implemented)
+ *    * XEN_DOMCTL_irq_permission (not yet implemented)
+ *
+ *  HYPERVISOR_sched_op
+ *   All generic sub-operations, with the exception of:
+ *    * SCHEDOP_block -- prefer wfi hardware instruction
+ *
+ *  HYPERVISOR_console_io
+ *   All generic sub-operations
+ *
+ *  HYPERVISOR_xen_version
+ *   All generic sub-operations
+ *
+ *  HYPERVISOR_event_channel_op
+ *   All generic sub-operations
+ *
+ *  HYPERVISOR_physdev_op
+ *   No sub-operations are currenty supported
+ *
+ *  HYPERVISOR_sysctl
+ *   All generic sub-operations, with the exception of:
+ *    * XEN_SYSCTL_page_offline_op
+ *    * XEN_SYSCTL_get_pmstat
+ *    * XEN_SYSCTL_pm_op
+ *
+ *  HYPERVISOR_hvm_op
+ *   Exactly these sub-operations are supported:
+ *    * HVMOP_set_param
+ *    * HVMOP_get_param
+ *
+ *  HYPERVISOR_grant_table_op
+ *   All generic sub-operations
+ *
+ *  HYPERVISOR_vcpu_op
+ *   Exactly these sub-operations are supported:
+ *    * VCPUOP_register_vcpu_info
+ *    * VCPUOP_register_runstate_memory_area
+ *
+ *
+ * Other notes on the ARM ABI:
+ *
+ * - struct start_info is not exported to ARM guests.
+ *
+ * - struct shared_info is mapped by ARM guests using the
+ *   HYPERVISOR_memory_op sub-op XENMEM_add_to_physmap, passing
+ *   XENMAPSPACE_shared_info as space parameter.
+ *
+ * - All the per-cpu struct vcpu_info are mapped by ARM guests using the
+ *   HYPERVISOR_vcpu_op sub-op VCPUOP_register_vcpu_info, including cpu0
+ *   struct vcpu_info.
+ *
+ * - The grant table is mapped using the HYPERVISOR_memory_op sub-op
+ *   XENMEM_add_to_physmap, passing XENMAPSPACE_grant_table as space
+ *   parameter. The memory range specified under the Xen compatible
+ *   hypervisor node on device tree can be used as target gpfn for the
+ *   mapping.
+ *
+ * - Xenstore is initialized by using the two hvm_params
+ *   HVM_PARAM_STORE_PFN and HVM_PARAM_STORE_EVTCHN. They can be read
+ *   with the HYPERVISOR_hvm_op sub-op HVMOP_get_param.
+ *
+ * - The paravirtualized console is initialized by using the two
+ *   hvm_params HVM_PARAM_CONSOLE_PFN and HVM_PARAM_CONSOLE_EVTCHN. They
+ *   can be read with the HYPERVISOR_hvm_op sub-op HVMOP_get_param.
+ *
+ * - Event channel notifications are delivered using the percpu GIC
+ *   interrupt specified under the Xen compatible hypervisor node on
+ *   device tree.
+ *
+ * - The device tree Xen compatible node is fully described under Linux
+ *   at Documentation/devicetree/bindings/arm/xen.txt.

+ * Event channels are the basic primitive provided by Xen for event
+ * notifications. An event is the Xen equivalent of a hardware
+ * interrupt. They essentially store one bit of information, the event
+ * of interest is signalled by transitioning this bit from 0 to 1.
+ *
+ * Notifications are received by a guest via an upcall from Xen,
+ * indicating when an event arrives (setting the bit). Further
+ * notifications are masked until the bit is cleared again (therefore,
+ * guests must check the value of the bit after re-enabling event
+ * delivery to ensure no missed notifications).
+ *
+ * Event notifications can be masked by setting a flag; this is
+ * equivalent to disabling interrupts and can be used to ensure
+ * atomicity of certain operations in the guest kernel.

+ * Event channels are represented by the evtchn_* fields in

+ * Xen's grant tables provide a generic mechanism to memory sharing
+ * between domains. This shared memory interface underpins the split
+ * device drivers for block and network IO.
+ *
+ * Each domain has its own grant table. This is a data structure that
+ * is shared with Xen; it allows the domain to tell Xen what kind of
+ * permissions other domains have on its pages. Entries in the grant
+ * table are identified by grant references. A grant reference is an
+ * integer, which indexes into the grant table. It acts as a
+ * capability which the grantee can use to perform operations on the
+ * granter’s memory.
+ *
+ * This capability-based system allows shared-memory communications
+ * between unprivileged domains. A grant reference also encapsulates
+ * the details of a shared page, removing the need for a domain to
+ * know the real machine address of a page it is sharing. This makes
+ * it possible to share memory correctly with domains running in
+ * fully virtualised memory.

+ *
+ * NB. WMB is a no-op on current-generation x86 processors. However, a
+ *     compiler barrier will still be required.
+ *
+ * Introducing a valid entry into the grant table:
+ *  1. Write ent->domid.
+ *  2. Write ent->frame:
+ *      GTF_permit_access:   Frame to which access is permitted.
+ *      GTF_accept_transfer: Pseudo-phys frame slot being filled by new
+ *                           frame, or zero if none.
+ *  3. Write memory barrier (WMB).
+ *  4. Write ent->flags, inc. valid type.
+ *
+ * Invalidating an unused GTF_permit_access entry:
+ *  1. flags = ent->flags.
+ *  2. Observe that !(flags & (GTF_reading|GTF_writing)).
+ *  3. Check result of SMP-safe CMPXCHG(&ent->flags, flags, 0).
+ *  NB. No need for WMB as reuse of entry is control-dependent on success of
+ *      step 3, and all architectures guarantee ordering of ctrl-dep writes.
+ *
+ * Invalidating an in-use GTF_permit_access entry:
+ *  This cannot be done directly. Request assistance from the domain controller
+ *  which can set a timeout on the use of a grant entry and take necessary
+ *  action. (NB. This is not yet implemented!).
+ *
+ * Invalidating an unused GTF_accept_transfer entry:
+ *  1. flags = ent->flags.
+ *  2. Observe that !(flags & GTF_transfer_committed). [*]
+ *  3. Check result of SMP-safe CMPXCHG(&ent->flags, flags, 0).
+ *  NB. No need for WMB as reuse of entry is control-dependent on success of
+ *      step 3, and all architectures guarantee ordering of ctrl-dep writes.
+ *  [*] If GTF_transfer_committed is set then the grant entry is 'committed'.
+ *      The guest must /not/ modify the grant entry until the address of the
+ *      transferred frame is written. It is safe for the guest to spin waiting
+ *      for this to occur (detect by observing GTF_transfer_completed in
+ *      ent->flags).
+ *
+ * Invalidating a committed GTF_accept_transfer entry:
+ *  1. Wait for (ent->flags & GTF_transfer_completed).
+ *
+ * Changing a GTF_permit_access from writable to read-only:
+ *  Use SMP-safe CMPXCHG to set GTF_readonly, while checking !GTF_writing.

+ * Older implementation of Xen network frontend / backend has an
+ * implicit dependency on the MAX_SKB_FRAGS as the maximum number of
+ * ring slots a skb can use. Netfront / netback may not work as
+ * expected when frontend and backend have different MAX_SKB_FRAGS.
+ *
+ * A better approach is to add mechanism for netfront / netback to
+ * negotiate this value. However we cannot fix all possible
+ * frontends, so we need to define a value which states the minimum
+ * slots backend must support.
+ *
+ * The minimum value derives from older Linux kernel's MAX_SKB_FRAGS
+ * (18), which is proved to work with most frontends. Any new backend
+ * which doesn't negotiate with frontend should expect frontend to
+ * send a valid packet using slots up to this value.

+ * Notifications after enqueuing any type of message should be conditional on
+ * the appropriate req_event or rsp_event field in the shared ring.
+ * If the client sends notification for rx requests then it should specify
+ * feature 'feature-rx-notify' via xenbus. Otherwise the backend will assume
+ * that it cannot safely queue packets (as it may not be kicked to send them).
+ */
+
+/*
+ * "feature-split-event-channels" is introduced to separate guest TX
+ * and RX notification. Backend either doesn't support this feature or
+ * advertises it via xenstore as 0 (disabled) or 1 (enabled).
+ *
+ * To make use of this feature, frontend should allocate two event
+ * channels for TX and RX, advertise them to backend as
+ * "event-channel-tx" and "event-channel-rx" respectively. If frontend
+ * doesn't want to use this feature, it just writes "event-channel"
+ * node as before.
+ */
+
+/*
+ * Multiple transmit and receive queues:
+ * If supported, the backend will write the key "multi-queue-max-queues" to
+ * the directory for that vif, and set its value to the maximum supported
+ * number of queues.
+ * Frontends that are aware of this feature and wish to use it can write the
+ * key "multi-queue-num-queues", set to the number they wish to use, which
+ * must be greater than zero, and no more than the value reported by the backend
+ * in "multi-queue-max-queues".
+ *
+ * Queues replicate the shared rings and event channels.
+ * "feature-split-event-channels" may optionally be used when using
+ * multiple queues, but is not mandatory.
+ *
+ * Each queue consists of one shared ring pair, i.e. there must be the same
+ * number of tx and rx rings.
+ *
+ * For frontends requesting just one queue, the usual event-channel and
+ * ring-ref keys are written as before, simplifying the backend processing
+ * to avoid distinguishing between a frontend that doesn't understand the
+ * multi-queue feature, and one that does, but requested only one queue.
+ *
+ * Frontends requesting two or more queues must not write the toplevel
+ * event-channel (or event-channel-{tx,rx}) and {tx,rx}-ring-ref keys,
+ * instead writing those keys under sub-keys having the name "queue-N" where
+ * N is the integer ID of the queue for which those keys belong. Queues
+ * are indexed from zero. For example, a frontend with two queues and split
+ * event channels must write the following set of queue-related keys:
+ *
+ * /local/domain/1/device/vif/0/multi-queue-num-queues = "2"
+ * /local/domain/1/device/vif/0/queue-0 = ""
+ * /local/domain/1/device/vif/0/queue-0/tx-ring-ref = "<ring-ref-tx0>"
+ * /local/domain/1/device/vif/0/queue-0/rx-ring-ref = "<ring-ref-rx0>"
+ * /local/domain/1/device/vif/0/queue-0/event-channel-tx = "<evtchn-tx0>"
+ * /local/domain/1/device/vif/0/queue-0/event-channel-rx = "<evtchn-rx0>"
+ * /local/domain/1/device/vif/0/queue-1 = ""
+ * /local/domain/1/device/vif/0/queue-1/tx-ring-ref = "<ring-ref-tx1>"
+ * /local/domain/1/device/vif/0/queue-1/rx-ring-ref = "<ring-ref-rx1"
+ * /local/domain/1/device/vif/0/queue-1/event-channel-tx = "<evtchn-tx1>"
+ * /local/domain/1/device/vif/0/queue-1/event-channel-rx = "<evtchn-rx1>"
+ *
+ * If there is any inconsistency in the XenStore data, the backend may
+ * choose not to connect any queues, instead treating the request as an
+ * error. This includes scenarios where more (or fewer) queues were
+ * requested than the frontend provided details for.
+ *
+ * Mapping of packets to queues is considered to be a function of the
+ * transmitting system (backend or frontend) and is not negotiated
+ * between the two. Guests are free to transmit packets on any queue
+ * they choose, provided it has been set up correctly. Guests must be
+ * prepared to receive packets on any queue they have requested be set up.

+ *                     (x) encodes the PFD as follows:
+ *                     x == 0 => PFD == DOMID_SELF
+ *                     x != 0 => PFD == x - 1
+ *
+ * Sub-commands: ptr[1:0] specifies the appropriate MMU_* command.
+ * -------------
+ * ptr[1:0] == MMU_NORMAL_PT_UPDATE:
+ * Updates an entry in a page table belonging to PFD. If updating an L1 table,
+ * and the new table entry is valid/present, the mapped frame must belong to
+ * FD. If attempting to map an I/O page then the caller assumes the privilege
+ * of the FD.
+ * FD == DOMID_IO: Permit /only/ I/O mappings, at the priv level of the caller.
+ * FD == DOMID_XEN: Map restricted areas of Xen's heap space.
+ * ptr[:2]  -- Machine address of the page-table entry to modify.
+ * val      -- Value to write.
+ *
+ * There also certain implicit requirements when using this hypercall. The
+ * pages that make up a pagetable must be mapped read-only in the guest.
+ * This prevents uncontrolled guest updates to the pagetable. Xen strictly
+ * enforces this, and will disallow any pagetable update which will end up
+ * mapping pagetable page RW, and will disallow using any writable page as a
+ * pagetable. In practice it means that when constructing a page table for a
+ * process, thread, etc, we MUST be very dilligient in following these rules:
+ *  1). Start with top-level page (PGD or in Xen language: L4). Fill out
+ *      the entries.
+ *  2). Keep on going, filling out the upper (PUD or L3), and middle (PMD
+ *      or L2).
+ *  3). Start filling out the PTE table (L1) with the PTE entries. Once
+ *  	done, make sure to set each of those entries to RO (so writeable bit
+ *  	is unset). Once that has been completed, set the PMD (L2) for this
+ *  	PTE table as RO.
+ *  4). When completed with all of the PMD (L2) entries, and all of them have
+ *  	been set to RO, make sure to set RO the PUD (L3). Do the same
+ *  	operation on PGD (L4) pagetable entries that have a PUD (L3) entry.
+ *  5). Now before you can use those pages (so setting the cr3), you MUST also
+ *      pin them so that the hypervisor can verify the entries. This is done
+ *      via the HYPERVISOR_mmuext_op(MMUEXT_PIN_L4_TABLE, guest physical frame
+ *      number of the PGD (L4)). And this point the HYPERVISOR_mmuext_op(
+ *      MMUEXT_NEW_BASEPTR, guest physical frame number of the PGD (L4)) can be
+ *      issued.
+ * For 32-bit guests, the L4 is not used (as there is less pagetables), so
+ * instead use L3.
+ * At this point the pagetables can be modified using the MMU_NORMAL_PT_UPDATE
+ * hypercall. Also if so desired the OS can also try to write to the PTE
+ * and be trapped by the hypervisor (as the PTE entry is RO).
+ *
+ * To deallocate the pages, the operations are the reverse of the steps
+ * mentioned above. The argument is MMUEXT_UNPIN_TABLE for all levels and the
+ * pagetable MUST not be in use (meaning that the cr3 is not set to it).
+ *
+ * ptr[1:0] == MMU_MACHPHYS_UPDATE:
+ * Updates an entry in the machine->pseudo-physical mapping table.
+ * ptr[:2]  -- Machine address within the frame whose mapping to modify.
+ *             The frame must belong to the FD, if one is specified.
+ * val      -- Value to write into the mapping entry.
+ *
+ * ptr[1:0] == MMU_PT_UPDATE_PRESERVE_AD:
+ * As MMU_NORMAL_PT_UPDATE above, but A/D bits currently in the PTE are ORed
+ * with those in @val.
+ *
+ * @val is usually the machine frame number along with some attributes.
+ * The attributes by default follow the architecture defined bits. Meaning that
+ * if this is a X86_64 machine and four page table layout is used, the layout
+ * of val is:
+ *  - 63 if set means No execute (NX)
+ *  - 46-13 the machine frame number
+ *  - 12 available for guest
+ *  - 11 available for guest
+ *  - 10 available for guest
+ *  - 9 available for guest
+ *  - 8 global
+ *  - 7 PAT (PSE is disabled, must use hypercall to make 4MB or 2MB pages)
+ *  - 6 dirty
+ *  - 5 accessed
+ *  - 4 page cached disabled
+ *  - 3 page write through
+ *  - 2 userspace accessible
+ *  - 1 writeable
+ *  - 0 present
+ *
+ *  The one bits that does not fit with the default layout is the PAGE_PSE
+ *  also called PAGE_PAT). The MMUEXT_[UN]MARK_SUPER arguments to the
+ *  HYPERVISOR_mmuext_op serve as mechanism to set a pagetable to be 4MB
+ *  (or 2MB) instead of using the PAGE_PSE bit.
+ *
+ *  The reason that the PAGE_PSE (bit 7) is not being utilized is due to Xen
+ *  using it as the Page Attribute Table (PAT) bit - for details on it please
+ *  refer to Intel SDM 10.12. The PAT allows to set the caching attributes of
+ *  pages instead of using MTRRs.
+ *
+ *  The PAT MSR is as follows (it is a 64-bit value, each entry is 8 bits):
+ *                    PAT4                 PAT0
+ *  +-----+-----+----+----+----+-----+----+----+
+ *  | UC  | UC- | WC | WB | UC | UC- | WC | WB |  <= Linux
+ *  +-----+-----+----+----+----+-----+----+----+
+ *  | UC  | UC- | WT | WB | UC | UC- | WT | WB |  <= BIOS (default when machine boots)
+ *  +-----+-----+----+----+----+-----+----+----+
+ *  | rsv | rsv | WP | WC | UC | UC- | WT | WB |  <= Xen
+ *  +-----+-----+----+----+----+-----+----+----+
+ *
+ *  The lookup of this index table translates to looking up
+ *  Bit 7, Bit 4, and Bit 3 of val entry:
+ *
+ *  PAT/PSE (bit 7) ... PCD (bit 4) .. PWT (bit 3).
+ *
+ *  If all bits are off, then we are using PAT0. If bit 3 turned on,
+ *  then we are using PAT1, if bit 3 and bit 4, then PAT2..
+ *
+ *  As you can see, the Linux PAT1 translates to PAT4 under Xen. Which means
+ *  that if a guest that follows Linux's PAT setup and would like to set Write
+ *  Combined on pages it MUST use PAT4 entry. Meaning that Bit 7 (PAGE_PAT) is
+ *  set. For example, under Linux it only uses PAT0, PAT1, and PAT2 for the
+ *  caching as:
+ *
+ *   WB = none (so PAT0)
+ *   WC = PWT (bit 3 on)
+ *   UC = PWT | PCD (bit 3 and 4 are on).
+ *
+ * To make it work with Xen, it needs to translate the WC bit as so:
+ *
+ *  PWT (so bit 3 on) --> PAT (so bit 7 is on) and clear bit 3
+ *
+ * And to translate back it would:
+ *
+ * PAT (bit 7 on) --> PWT (bit 3 on) and clear bit 7.

+/**
+ * @file
+ *
+ * EFI SNP HII protocol
+ *
+ * The HII protocols are some of the less-well designed parts of the
+ * entire EFI specification.  This is a significant accomplishment.
+ *
+ * The face-slappingly ludicrous query string syntax seems to be
+ * motivated by the desire to allow a caller to query multiple drivers
+ * simultaneously via the single-instance HII_CONFIG_ROUTING_PROTOCOL,
+ * which is supposed to pass relevant subsets of the query string to
+ * the relevant drivers.
+ *
+ * Nobody uses the HII_CONFIG_ROUTING_PROTOCOL.  Not even the EFI
+ * setup browser uses the HII_CONFIG_ROUTING_PROTOCOL.  To the best of
+ * my knowledge, there has only ever been one implementation of the
+ * HII_CONFIG_ROUTING_PROTOCOL (as part of EDK2), and it just doesn't
+ * work.  It's so badly broken that I can't even figure out what the
+ * code is _trying_ to do.
+ *
+ * Fundamentally, the problem seems to be that Javascript programmers
+ * should not be allowed to design APIs for C code.

+/** @page rc80211 Rate control philosophy
+ *
+ * We want to maximize our transmission speed, to the extent that we
+ * can do that without dropping undue numbers of packets. We also
+ * don't want to take up very much code space, so our algorithm has to
+ * be pretty simple
+ *
+ * When we receive a packet, we know what rate it was transmitted at,
+ * and whether it had to be retransmitted to get to us.
+ *
+ * When we send a packet, we hear back how many times it had to be
+ * retried to get through, and whether it got through at all.
+ *
+ * Indications of TX success are more reliable than RX success, but RX
+ * information helps us know where to start.
+ *
+ * To handle all of this, we keep for each rate and each direction (TX
+ * and RX separately) some state information for the most recent
+ * packets on that rate and the number of packets for which we have
+ * information. The state is a 32-bit unsigned integer in which two
+ * bits represent a packet: 11 if it went through well, 10 if it went
+ * through with one retry, 01 if it went through with more than one
+ * retry, or 00 if it didn't go through at all. We define the
+ * "goodness" for a particular (rate, direction) combination as the
+ * sum of all the 2-bit fields, times 33, divided by the number of
+ * 2-bit fields containing valid information (16 except when we're
+ * starting out). The number produced is between 0 and 99; we use -1
+ * for rates with less than 4 RX packets or 1 TX, as an indicator that
+ * we do not have enough information to rely on them.
+ *
+ * In deciding which rates are best, we find the weighted average of
+ * TX and RX goodness, where the weighting is by number of packets
+ * with data and TX packets are worth 4 times as much as RX packets.
+ * The weighted average is called "net goodness" and is also a number
+ * between 0 and 99.  If 3 consecutive packets fail transmission
+ * outright, we automatically ratchet down the rate; otherwise, we
+ * switch to the best rate whenever the current rate's goodness falls
+ * below some threshold, and try increasing our rate when the goodness
+ * is very high.
+ *
+ * This system is optimized for iPXE's style of usage. Because normal
+ * operation always involves receiving something, we'll make our way
+ * to the best rate pretty quickly. We tend to follow the lead of the
+ * sending AP in choosing rates, but we won't use rates for long that
+ * don't work well for us in transmission. We assume iPXE won't be
+ * running for long enough that rate patterns will change much, so we
+ * don't have to keep time counters or the like.  And if this doesn't
+ * work well in practice there are many ways it could be tweaked.
+ *
+ * To avoid staying at 1Mbps for a long time, we don't track any
+ * transmitted packets until we've set our rate based on received
+ * packets.

+ *
+ * Peer Content Caching and Retrieval: Discovery Protocol [MS-PCCRD]
+ *
+ * This protocol manages to ingeniously combine the excessive
+ * verbosity of XML with a paucity of actual information.  For
+ * example: even in version 2.0 of the protocol it is still not
+ * possible to discover which peers hold a specific block within a
+ * given segment.
+ *
+ * For added bonus points, version 1.0 of the protocol is specified to
+ * use a case-sensitive string comparison (for SHA2 digest values) but
+ * nothing specifies whether the strings in question should be in
+ * upper or lower case.  There are example strings given in the
+ * specification, but the author skilfully manages to leave the issue
+ * unresolved by using the somewhat implausible digest value of
+ * "0200000000000000000000000000000000000000000000000000000000000000".
+ *
+ * Just in case you were thinking that the silver lining of the choice
+ * to use an XML-based protocol would be the ability to generate and
+ * process messages with standard tools, version 2.0 of the protocol
+ * places most of the critical information inside a Base64-encoded
+ * custom binary data structure.  Within an XML element, naturally.
+ *
+ * I hereby announce this specification to be the 2015 winner of the
+ * prestigious "UEFI HII API" award for incompetent design.

+ *

+ * Scalable Local Area Multicast protocol
+ *
+ * The SLAM protocol is supported only by Etherboot; it was designed
+ * and implemented by Eric Biederman.  A server implementation is
+ * available in contrib/mini-slamd.  There does not appear to be any
+ * documentation beyond a few sparse comments in Etherboot's
+ * proto_slam.c.
+ *
+ * SLAM packets use three types of data field:
+ *
+ *  Nul : A single NUL (0) byte, used as a list terminator
+ *
+ *  Raw : A block of raw data
+ *
+ *  Int : A variable-length integer, in big-endian order.  The length
+ *        of the integer is encoded in the most significant three bits.
+ *
+ * Packets received by the client have the following layout:
+ *
+ *  Int : Transaction identifier.  This is an opaque value.
+ *
+ *  Int : Total number of bytes in the transfer.
+ *
+ *  Int : Block size, in bytes.
+ *
+ *  Int : Packet sequence number within the transfer (if this packet
+ *        contains data).
+ *
+ *  Raw : Packet data (if this packet contains data).
+ *
+ * Packets transmitted by the client consist of a run-length-encoded
+ * representation of the received-blocks bitmap, looking something
+ * like:
+ *
+ *  Int : Number of consecutive successfully-received packets
+ *  Int : Number of consecutive missing packets
+ *  Int : Number of consecutive successfully-received packets
+ *  Int : Number of consecutive missing packets
+ *  ....
+ *  Nul

+	 * IMPORTANT NOTE
+	 *
+	 * The NIST test vector set includes several calls to
+	 * HMAC_DRBG_Generate() that are expected to fail with a
+	 * status of "Reseed required".  The pattern seems to be that
+	 * when prediction resistance is requested, any call to
+	 * HMAC_DRBG_Generate() is at first expected to fail.  After
+	 * an explicit reseeding, the call to HMAC_DRBG_Generate() is
+	 * retried, and on this second time it is expected to succeed.
+	 *
+	 * This pattern does not match the specifications for
+	 * HMAC_DRBG_Generate(): neither HMAC_DRBG_Generate_algorithm
+	 * (defined in ANS X9.82 Part 3-2007 Section 10.2.2.2.5 (NIST
+	 * SP 800-90 Section 10.1.2.5)) nor the higher-level wrapper
+	 * Generate_function defined in ANS X9.82 Part 3-2007 Section
+	 * 9.4 (NIST SP 800-90 Section 9.3)) can possibly exhibit this
+	 * behaviour:
+	 *
+	 * a) HMAC_DRBG_Generate_algorithm can return a "reseed
+	 *    required" status only as a result of the test
+	 *
+	 *      "1. If reseed_counter > reseed_interval, then return
+	 *       an indication that a reseed is required."
+	 *
+	 *    Since the reseed interval is independent of any request
+	 *    for prediction resistance, and since the reseed interval
+	 *    is not specified as part of the NIST test vector set,
+	 *    then this cannot be the source of the "Reseed required"
+	 *    failure expected by the NIST test vector set.
+	 *
+	 * b) Generate_function cannot return a "reseed required"
+	 *    status under any circumstances.  If the underlying
+	 *    HMAC_DRBG_Generate_algorithm call returns "reseed
+	 *    required", then Generate_function will automatically
+	 *    reseed and try again.
+	 *
+	 * To produce the behaviour expected by the NIST test vector
+	 * set, we therefore contrive to produce a "reseed required"
+	 * state where necessary by setting the reseed_counter to
+	 * greater than the reseed_interval.
