Many ed-based Ethernet PC-cards can't get correct MAC address without

For example, when /etc/pccard.conf had ed0 in config line, but kernel
refused this name and said
devclass_alloc_unit: ed0 already exists, using next availale unit
number
Kernel used ed1 as device name and it did not match with config and
insert/remove lines. Fortunately, dhclient was called without args,
and it works, but if we wanted to use static IP address for PC-card,
it did not work.
This modification makes pccardd to execute insert/remove lines with
the true device name that returns from kernel. (Last change to
etc/pccard.conf.sample eliminated all hardwired device name from
insert/remove lines in /etc/pccard.conf)

This makes the ed driver not enter its interrupt routine during the
probe. Apparently, an interrupt happens when you disable the
interrupts. There are other problems with ed still.

Should have no effect, but does make things a little cleaner. I
thought this was the race that was causing problems, but it turned out
to be in pccardd waking up after the empty/insert events had happened
and being confused.
Minor cleanup:
o Remove isahd from pccard_devinfo
o remove extra from controller
o formatting nits
o use PCCARD_DEVINFO(d) rather than a bare device_get_ivars(d)

as the unit argument instead of 0. disable_slot() calls
devclass_get_device() correctly, however because alloc_driver() does
it wrong, disable_slot() is unable to locate the child devices
attached to the pccard bus and thus fails to call device_delete_child()
on them. The end result is that when a card is removed, its detach
routine is never called, and re-insertion always fails.
With this fix (and the previous one to if_wi.c), I can now insert,
remove and re-insert my WaveLAN/IEEE card and things behave correctly.
kldunloading the if_wi.ko module also seems to work properly now.

device_add_child_ordered(). 'ivars' may now be set using the
device_set_ivars() function.
This makes it easier for us to change how arbitrary data structures are
associated with a device_t. Eventually we won't be modifying device_t
to add additional pointers for ivars, softc data etc.
Despite my best efforts I've probably forgotten something so let me know
if this breaks anything. I've been running with this change for months
and its been quite involved actually isolating all the changes from
the rest of the local changes in my tree.

problem.
o Create new timeout routine so we don't detach the card inside a ISR
but instead drop back to spl0 via a timeout of 0.
o Actually delete the child of the pccard device rather than just faking
it badly.
o Fix sio, ed and ep to have pccard detach routines that are int rather
than void.
o Fix ep and ed pccard detach routines to use if_detach rather than just
if_down. if_detach destroys the device, while if_down just marks it
down. In this incarnation of the pccard things, we map the disable
the slot action to detach the driver, which removes the driver from the
device tree. When that is done, a panic would soon follow as the
ifconfig tried to down the device.
Didn't fix:
o Should cache the pccard dev child's pointer in struct slot
o remove now unused parts of struct slot
o Any driver using softc after detach has been called. sio's softc used
to be statically allocated, so you could check sc->gone, but that is
now gone.
o Didn't remove gone from softc of drivers that use the old pccard method.
Didn't test:
o ed driver changes
o sio driver changes on pccards
o suspend (no laptop or apm support on my desktop)

o Gut the compatibility interface, you now must attach with newbus.
o Unit numbers from pccardd are now ignored. This may change the units
assigned to a card. It now uses the first available unit.
o kill old skeleton code that is now obsolete.
o Use newbus attachment code.
o cleanup interfile dependencies some.
o kill list of devices per slot. we use the device tree for what we need.
o Remove now obsolete code.
o The ep driver (and maybe ed) may need some config file tweaks to
allow it to attach. See config files that were committed for examples
on how to do this.
Drivers to be commited shortly.
This is an interrum fix until the new pccard. ed, ep and sio will be
supported by me with this release, although others are welcome to try
to support other devices before new pccard is working.
I plan on doing minimal further work on this code base. Be careful
when upgrading, since this code is known to work on my laptop and
those of a couple others as well, but your milage may vary.
BUGS TO BE FIXED:
o system memory isn't allocated yet, it will be soon.
o No devices actually have a pccard newbus attach in the tree.
BUGS THAT MIGHT BE FIXED:
o card removal, including suspend, usually hangs the system.
Many thanks to Peter Wemm and Doug Rabson for helping me to fill in
the missing bits of New Bus understanding at FreeBSD Con '99.

floating before). Attach pccard devices to pcic, one per slot
(although this may change to one per pcic). pcic is now attached to
isa (to act as a bridge) and pccard is attached to pcic, cbb and
pc98ic (the last two are card bus bridge and the pc98ic version of
pcic, neither of which are in the tree yet). Move pccard compat code
into pccard/pccard_compat.c.
THIS REQUIRES A CONFIG FILE CHANGE. You must change your pcic/card
entries to be:
# PCCARD (PCMCIA) support
controller pcic0 at isa?
controller pcic1 at isa?
controller card0
The old system was upside down and this corrects that problem. It
will make it easier to add support for YENTA pccard/card bus bridges.
Much more cleanup needs to happen before newbus devices can have
pccard attachments. My previous commit's comments were premature.

Add the correct hook for devfs to kern_conf.c
The net result of this excercise is that a lot less files depends on DEVFS,
and devtoname() gets more sensible output in many cases.
A few drivers had minor additional cleanups performed relating to cdevsw
registration.
A few drivers don't register a cdevsw{} anymore, but only use make_dev().

The cdevsw_add() function now finds the major number(s) in the
struct cdevsw passed to it. cdevsw_add_generic() is no longer
needed, cdevsw_add() does the same thing.
cdevsw_add() will print an message if the d_maj field looks bogus.
Remove nblkdev and nchrdev variables. Most places they were used
bogusly. Instead check a dev_t for validity by seeing if devsw()
or bdevsw() returns NULL.

.. to 2.2.x and 3.x if people think it's worth it. Driver writers can do
this if it's not defined. (The reason for this is that I'm trying to
progressively eliminate use of linker_sets where it hurts modularity and
runtime load capability, and these DATA_SET's keep getting in the way.)

abuses its argument, which is supposed to be an integer unit number, as
a pointer to the head of the 'struct slot' list. When this code was
hacked^Wupdated for newbus, a new mechanism for registering slot_irq_handler()
was put in place and the significance of the unit number was overlooked.
When registering an interrupt, we have both device_id and unit. The unit
number is passed as 'unit' but /sys/i386/usa/intr_machdep.c:register_intr()
drops unit on the floor and uses device_id instead. Since pccard_alloc_intr()
always sets device_id to 0, this means the unit number is always zero, and
slot_irq_handler() is always called with 0, which becomes a NULL pointer
which slot_irq_handler() tries to dereference and the kernel explodes.
Result: if you assign a PCMCIA driver in the kernel config file like this:
device wi0 at isa? port? irq?
Then the system will panic the moment a PCMCIA device is attached and
an interrupt is triggered.
The quick fix: make pccard_alloc_intr() pass the unit number as both
the device_id and unit arguments to register_pcic_intr(). The correct fix
would be to rewrite /sys/pccard to be less disgusting.
