Also eliminate redundant warnings about conflicts.

fxp_stop is called as the first thing in fxp_init, and if the tx desc
list has junk in it, the system may panic. This bug showed up as a side
effect of the changes in rev 1.56, but has been in the code since the
beginning.
this myself for ages, but wasn't able to get any feedback from the people
that I sent it to for testing.
Guy Helmer <ghelmer@scl.ameslab.gov> has given it a shot (before getting on
a plane, thanks!) and it appears to stop his reproducable page fault panic
in the testing he was able to do.
o For bt and aha only probe the one I/O range if a specific I/O is specified
in the config file.
o Don't even try to probe I/O ranges that have been seen already.
o If we conflict with an IRQ or DRQ, then fail the probe.

is a work-around from an LRAM access bug on the 940UA. In a future
microcode revision, the high 16bits of residual information will be moved
to a safe location and we'll return to 32bit residuals. Since we only
allow 64KB I/O, 16bits is enough.

a similar treatment, and many more that should be converted to plain
log messages (e.g. "WARNING: wrintr but write DMA inactive!"). Now
that I think of it, same goes for the CAM code (e.g. the famed "tagged
openings" message)
Disable DPARCKEN in the DSCOMMAND0 register on the aic7890/91/96/97.
Parity checking is broken for some chip/MB combinations and this
is the work around recommended by Adaptec.

Perform dma segment setup outside of splcam protection as this can take

At using tcpdump for cs interface, tcpdump only dump packet which
src or dst MAC-address is cs interface. cs interface can't look up
packet between others.

add support for Vibra16X, OPTi925, and bring in several assorted
fixes to the code and documentation.
Also present here are apm hooks so that laptops can properly
reconfigure the hardware after suspend (tested on the Libretto50).

- Express various sizes in bytes, rather than Kbytes, in the video
mode and adapter information structures.
- Fill 0 in the linear buffer size field if the linear frame buffer
is not available.
- Remove SW_VESA_USER ioctl. It is still experimetal and was not meant
to be released.
- Fix missing cast operator.
- Correctly handle pointers returned by the VESA BIOS. The pointers
may point to the area either in the BIOS ROM or in the buffer supplied
by the caller.
- Set the destructive cursor at the right moment.
o Use the board id command to find out what kind of board
we're talking to. If we're talking to a board that is has
an ID that is shared between boards supported by the aha
driver and the bt driver, then use the bt's geometry
register to weed out the bt cards. Otherwise assume that we
support this card.
o Remove bt esetup command sending to the card. It seems to
wedge too many cards.
o Revert to doing a soft reset after an invalid command. This
change didn't fix anything, so I'm backing it out. The
whole issue of card resetting needs to be revisisted at some
point so that we can do it properly on all hardware.
o GC unused stuff in some places.
o Unlock mailbox interface if we have a new card. Before only newer cards
(B or newer) that had the BIOS disabled would probe. Cards with the
BIOS enabled would fail to probe in the mailbox initialization code.
o Increase the number of ccbs and sg to 17 from 16 to support 64k I/O
on a non page aligned boundary. Ideas for dynamic determination of this
value welcomed, as more of these are better.
o Took credit for this driver, even though I derived it from Justin's code.
Made sure that Justin's copyright from bt.c was preserved, along with
his name, since the error handling code is nearly identical. Add my
own, identical copyright. Point people to aha_isa.c.
Cards tested: 1542C and 1542CF. The B and CP might work now as well,
but logistical problems precluded me from testing them this evening
(if you have jumper settings for the B card, please send me private
mail).
- there were too many global variables (there still are :-).
- the data section was bloated by explicit initializations of static
variables to 0 (only fixed the recently changed ones).
- WRAPHIST() had silly parentheses around foo->bar.
- the comment about inline functions was stale.
- the comment about Userconfig presumes too much about the boot environment.
- `i' was reused confusingly in scioctl().
- the declaration of `butmap' used a deprecated K&R misfeature.
- the initializeation of `butmap' had an unnecessary line break.
- `unsigned char' was not consistently (mis)spelled as u_char.
- English was poor in a comment in videoio.c.
