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

o Took credit for this driver, even though I derived it from Justin's code.

his name, since the error handling code is nearly identical. Add my

these numbers to real video mode numbers appropriate and available
with the given video hardware. I believe this will be useful to make

+ cleanup (and fix a glaring bug) in the and of the dma setup
routine. Also, the dma setup routines either return CMD_QUEUED

(for requeuing for resource shortage reasons).

The vidcontrol command now accepts the following video mode names:
VESA_132x25, VESA_132x43, VESA_132x50, VESA_132x60, VESA_800x600
The VESA_800x600 mode is a raster display mode. The 80x25 text will
be displayed on the 800x600 screen. Useful for some laptop computers.
vidcontrol accepts the new `-i <info>' option, where <info> must be
either `adapter' or `mode'. When the `-i adapter' option is given,
vidcontrol will print basic information (not much) on the video
adapter. When the `-i mode' option is specified, vidcontrol will
list video modes which are actually supported by the video adapter.

Add a sysctl 'machdep.cs_recv_delay' to specify how long to wait after
receiving a packet in order to check for a subsequent (back-to-back)
packet. The cs8900 has a very small receive buffer, so this helps avoid
overflows at the cost of some extra CPU overhead.

for the Lite2 fix for always returning EIO in dead_read().
Cleaned up the cdevswitch initializers for all tty drivers.
Removed explicit calls to ttsetwater() from all (tty) drivers. ttsetwater()
is now called centrally for opens, not just for parameter changes.
The check for dropping unicast packets not sent to our ethernet
address is after the bpf tap, but not conditioned on it. All packets
received should get handed to bpf, and unicast packets not to us (mac)
should get dropped whether or not there is a bpf listener. I believe
that the common optimization that the interface is in hw promisc mode
iff there is a bpf listener is in general wrong, but more frequently
so on wavelans.
I think Max's fix makes bpf listeners not see unicast packets sent to
others, but I'm not sure.
One can argue that checking on MOD_ENAL is wrong, but the code only
drops packets that shouldn't be received. The correctness condition
is that it be run whenever unicast packets without our mac address can
be received.
