Add softc flag to indicate that we have seen at
least one selection since the last bus reset or
SE/LVD bus change.
aic79xx.c:
Fix a few style nits.
In ahd_update_pending_scbs(), only touch card registers
once we have found an SCB that needs to be updated.
This removes lots of clutter from PCI traces taken of
error recovery performed by the driver.
Short circuit the first selection iocell workaround handler
if we've run once since the last bus reset or iocell change.
This also removes clutter from PCI traces.
Note if completions are pending in the qoutfifo when we dump
card state.
Add a comment in ahd_clear_critical_sections() about
our need to leave ENBUSFREE set in SIMODE1 while single
stepping.
Re-arrange some delay loops so that we always perform
a read after any register write and before the delay.
This should make the delay loop more accurate.
When completing message processing for a packetized
commention, return the controller to a state where
invalid non-packetized phases will still cause protocol
violations. These are the same operations as those
performed in the clear_target_state routine in the
firmware.
Now that we have a chip with working ABORTPENDING
support (the 7901B), comment out the automatic use
of this feature until we can adequately test it.
The previous checkin updated the bug mask for the
7901B so this code was exercised.
When resetting the bus, perform an ahd_flush_device_writes()
call so that our reset assertion delay is acurately
timed from when the reset bit is written to the controller.
Remove an old comment that no longer applies.
Fix a jump in our unexpected non-packetized phase
handler to use an explicit lable. The old code
had a hardcoded jump offset that was off by one
instruction.
Add a 7901A specific feature definition.
aic79xx_pci.c:
Split out the general aic790X setup into it's own
setup handler that works on single and dual controllers.
Adjust all other PCI setup handlers to initialize the
chips basic features and type before calling the generic
handler.
Turn off a few Rev B workarounds that are not required
on the 7901B.

succeeds. There is a difference between how OLDCARD and NEWCARD deal
with their resources, and this code exposes that difference. I'm not
sure which behavior is correct, and will need to look into that in
more detail. However, it appears that we go ahead and allocate the
right thing in both cases that I have access to (CF cards, CDROM, and
external ata enclosures), so go ahead and ignore the failure to get
the resource for the other rid. There's already another check to make
sure that the actual allocation works correctly, and that should be
sufficient to catch cases that don't work.

o add back rx monitor support
o make WI_RID_SCAN_RES DTRT
o fix a bug handling zero-length RID requests (used by dstumbler to set
a zero-length SSID)
o make RID_SCAN_REQ DTRT
o add back WI_RID_OWN_SSID
o fix wi_scan_ap to take a channel mask and txrate (for prism cards)
These changes fix dstumbler -o (monitor mode). A minor change to dstumbler
is needed to get normal AP scanning mode to work right; this is preferred to
modifying the driver.

flag'ed INTR_MPSAFE. In ep_if_start(), use the IF_DEQUEUE macro to
grab the next mbuf to send, and use IF_PREPEND if the card is busy
and we actually can't handle it right now.
The old code was first getting the mbuf by taking it from the queue
without using the macros, thus without locking, and without removing
it from the queue either. It was later assuming that IF_DEQUEUE would
give him this same mbuf.

fixes the net.isr.enable=1 case. Better performance might be
obtained by chaining all packets received, dropping the lock, and
then calling if_input() on each one.
