Correct an off by one in our critical section handling.
SEQADDR always reads the next instruction to execute,
so we must subtract one from its value before making
comparisons with entries in the critical section table.
Print a few additional registers whenever we dump
card state.
Show the SCB_CONTROL and SCB_TAG values for all pending
SCBs in card SCB ram when dumping card state.
aic7xxx.seq:
Fix a bug introduced while optimizing the SDPTR path.
We would ack the SDPTR message twice on Ultra2 or better
chips if it occurred after all data had been transferred
for a transaction.
Change our workaround for the PCI2.1 retry bug on some
chips. Although the previous workaround was logically
correct, its faster method of draining the FIFO seemed
to occassionally confuse the FIFO state. We now drain
the FIFO at half the speed which avoids the problem.
aic7xxx_pci.c:
Chips with the PCI 2.1 retry bug can't handle a 16byte
cachesize. If the cachesize is set to 16bytes, drop
it to 0.
Although it can go higher, it is not safe to so do on arrays with many
members. Compromise by adding a tunable, "hw.aac.iosize_max" that can be
set at boottime. Also document in the aac(4) manpage.

problems that we were seeing on our production server. These patches have
been tested for almost 6 months and are a highly recommended MFC candidate.

Then we rename cur_XXXX to actv_XXXX (these are the currently active settings)

This probably isn't entirely final as yet- but it's a lot closer to now
being what it should be, including allowing camcontrol to actually set
specific settings.

blown over by the Hurricane and had a house dropped on you by the Tornado.
Now it's time to have your parade rained on by... the Typhoon!
This commit adds driver support for 3Com 3cR990 10/100 ethernet
adapters based on the Typhoon I and Typhoon II chipsets. This is actually
a port of the OpenBSD driver with many hacks by me.
No Virginia, there isn't any support for the hardware crypto yet. However
there is support for TCP/IP checksum offload and VLANs.
Special thanks go to Jason Wright, Aaron Campbell and Theo de Raadt for
squeezing enough info out of 3Com to get this written, and for doing
most of the hard work.
Manual page is included. Compiled as a module and included in GENERIC.
