+ add a missing call to dn_rule_delete() when flushing firewall
rules, thus preventing possible panics due to dangling pointers
(this was already done for single rule deletes).
+ improve "usage" output in ipfw(8)
+ add a few checks to ipfw pipe parameters and make it a bit more
tolerant of common mistakes (such as specifying kbit instead of Kbit)

manager and prevented IOPort allocation beyond the first EISA slot from
working. subr_rman.c should have trapped this on the way into the system
rather than tripping over the wreckage.

if there is no character device associated with the block device. In this
case that doesn't matter because bdevvp() doesn't use the character
device structure.
I can use the pointy bit of the axe too.
on systems with no FFS.
- Remove all references to mfs from cpu_rootconf(). mfs_init is
called prior to cpu_rootconf(), so it can set mountrootfsname to mfs
and (more imporantly) set rootdev using the (bogus in Bruce's opinion)
special major number of 255.
- Fix an error message.
- Do the MFS_ROOT setting of mountrootfsname in mfs_init() instead of
cpu_rootconf().
- Set rootdev in mfs_init instead of later in mfs_mount() iff MFS_ROOT.
Honor the 'bus reset at startup' option now that the XPT properly

Honor the sync rate settings on Ultra2 controllers. We would
always negotiate at the fastest speed. Oops.

Release ATIO structures that wind up in the 'unkown command queue'

when the exception for that command is cleared.
types allow the reporting of error counts and other statistics. Currently
we provide information on the last BDR or bus reset as well as active
transaction inforamtion, but this will be expanded as more information is
added to aid in error recovery.
Use the 'last reset' information to better handle bus settle delays.
Peripheral drivers now control whether a bus settle delay occurs and
for how long. This allows target mode peripheral drivers to avoid
having their device queue frozen by the XPT for what shoudl only be
initiator type behavior.
Don't perform a bus reset if the target device is incapable of performing
transfer negotiation (e.g. Fiber Channel).
If we don't perform a bus reset but the controller is capable of transfer
negotiations, force negotiations on the first transaction to go to the
device. This ensures that we aren't tripped up by a left over negotiation
from the prom, BIOS, loader, etc.
Add a default async handler funstion to cam_periph.c to remove duplicated
code in all initiator type peripheral drivers.
Allow mapping of XPT_CONT_TARGET_IO ccbs from userland. They are
itentical to XPT_SCSI_IO ccbs as far as data mapping is concerned.
driver lacks error recovery and still needs more testing, but it's
about time I got it under revision control.

ADMtek AL981 "Comet" chipset. The AL981 is yet another DEC tulip clone,
except with simpler receive filter options. The AL981 has a built-in
transceiver, power management support, wake on LAN and flow control.
This chip performs extremely well; it's on par with the ASIX chipset
in terms of speed, which is pretty good (it can do 11.5MB/sec with TCP
easily).
I would have committed this driver sooner, except I ran into one problem
with the AL981 that required a workaround. When the chip is transmitting
at full speed, it will sometimes wedge if you queue a series of packets
that wrap from the end of the transmit descriptor list back to the
beginning. I can't explain why this happens, and none of the other tulip
clones behave this way. The workaround this is to just watch for the end
of the transmit ring and make sure that al_start() breaks out of its
packet queuing loop and waiting until the current batch of transmissions
completes before wrapping back to the start of the ring. Fortunately, this
does not significantly impact transmit performance.
This is one of those things that takes weeks of analysis just to come
up with two or three lines of code changes.

Fixed problems:
LS120/ZIP drives still currupted data.
Reworked once again, buffered I/O is just ignoring any sizehints
it is given :(
Now the atapifd driver splits up requests for devices that has
limitted transfer size.
ISA only configs fails on boot with interrupt timeouts.
The new-bus integration introduced a bug where the softc ptr

Some minor cleanups and rearrangements as well.
As usual USE AT YOUR OWN RISK!!, this is still pre alpha level code.
Especially the DMA support can hose your disk real bad if anything

Notebook owners should be carefull that their machines dont suspend

But please tell me how it works for you!
