-/*
-				Theory of Operation
-
-I. Board Compatibility
-
-This driver is for the Adaptec 6915 "Starfire" 64 bit PCI Ethernet adapter.
-
-II. Board-specific settings
-
-III. Driver operation
-
-IIIa. Ring buffers
-
-The Starfire hardware uses multiple fixed-size descriptor queues/rings.  The
-ring sizes are set fixed by the hardware, but may optionally be wrapped
-earlier by the END bit in the descriptor.
-This driver uses that hardware queue size for the Rx ring, where a large
-number of entries has no ill effect beyond increases the potential backlog.
-The Tx ring is wrapped with the END bit, since a large hardware Tx queue
-disables the queue layer priority ordering and we have no mechanism to
-utilize the hardware two-level priority queue.  When modifying the
-RX/TX_RING_SIZE pay close attention to page sizes and the ring-empty warning
-levels.
-
-IIIb/c. Transmit/Receive Structure
-
-See the Adaptec manual for the many possible structures, and options for
-each structure.  There are far too many to document all of them here.
-
-For transmit this driver uses type 0/1 transmit descriptors (depending
-on the 32/64 bitness of the architecture), and relies on automatic
-minimum-length padding.  It does not use the completion queue
-consumer index, but instead checks for non-zero status entries.
-
-For receive this driver uses type 2/3 receive descriptors.  The driver
-allocates full frame size skbuffs for the Rx ring buffers, so all frames
-should fit in a single descriptor.  The driver does not use the completion
-queue consumer index, but instead checks for non-zero status entries.
-
-When an incoming frame is less than RX_COPYBREAK bytes long, a fresh skbuff
-is allocated and the frame is copied to the new skbuff.  When the incoming
-frame is larger, the skbuff is passed directly up the protocol stack.
-Buffers consumed this way are replaced by newly allocated skbuffs in a later
-phase of receive.
-
-A notable aspect of operation is that unaligned buffers are not permitted by
-the Starfire hardware.  Thus the IP header at offset 14 in an ethernet frame
-isn't longword aligned, which may cause problems on some machine
-e.g. Alphas and IA64. For these architectures, the driver is forced to copy
-the frame into a new skbuff unconditionally. Copied frames are put into the
-skbuff at an offset of "+2", thus 16-byte aligning the IP header.
-
-IIId. Synchronization
-
-The driver runs as two independent, single-threaded flows of control.  One
-is the send-packet routine, which enforces single-threaded use by the
-dev->tbusy flag.  The other thread is the interrupt handler, which is single
-threaded by the hardware and interrupt handling software.
-
-The send packet thread has partial control over the Tx ring and the netif_queue
-status. If the number of free Tx slots in the ring falls below a certain number
-(currently hardcoded to 4), it signals the upper layer to stop the queue.
-
-The interrupt handler has exclusive control over the Rx ring and records stats
-from the Tx ring.  After reaping the stats, it marks the Tx queue entry as
-empty by incrementing the dirty_tx mark. Iff the netif_queue is stopped and the
-number of free Tx slow is above the threshold, it signals the upper layer to
-restart the queue.

-IVc. Errata
-
-- StopOnPerr is broken, don't enable
-- Hardware ethernet padding exposes random data, perform software padding
-  instead (unverified -- works correctly for all the hardware I have)
