the old (now invalid) mbuf to be passed to BPF_MTAP.

table, acquiring the necessary locks as it works. It usually returns
two references to the new descriptor: one in the descriptor table
and one via a pointer argument.
As falloc releases the FILEDESC lock before returning, there is a
potential for a process to close the reference in the file descriptor
table before falloc's caller gets to use the file. I don't think this
can happen in practice at the moment, because Giant indirectly protects
closes.
To stop the file being completly closed in this situation, this change
makes falloc set the refcount to two when both references are returned.
This makes life easier for several of falloc's callers, because the
first thing they previously did was grab an extra reference on the
file.

Use EP_{READ,WRITE}{,_MULTI}_{1,2,4} instead. I've had several people
submit patches like this over the years of varying qualities, markm
being the last. The names were chosen in consulation with mdodd on
irc.
I've tested this with only PCMCIA cards: 3CCE589EC and 3CCSH572BT.
I've not tried with my more extensive ISA, EISA and cbus collection.

Though this is still incomplete and has some missing features such as
exclusive login and event notification, it may be enough for someone
who wants to play with it.
This driver is supposed to work with firewire(4), targ(4) of CAM(4)
and scsi_target(8) which can be found in /usr/share/example/scsi_target.
This driver doesn't require sbp(4) which implements initiator mode.
Sample configuration:
Kernel: (you can use modules as well)
device firewire
device scbus
device targ
device sbp_targ
After reboot:
# mdconfig -a -t malloc -s 10m
md0
# scsi_target 0:0:0 /dev/md0
(Assuming sbp_targ0 on scbus0)
You should find the 10MB HDD on FreeBSD/MacOS X/WinXP or whatever connected
to the target using FireWire.

- Change type of target->luns to allocate an array of LUNs dynamically.
This allows targets to change their number of LUNs after each bus reset.
- Serialize ORB POINTER command for each LUN.
- Improve debug messages.
- Correct the logic for the AIF array index pointers so that correct slot is
always looked at.
- Copy the full FIB payload size when copying AIF's, not just the first 64
bytes.
Thanks to Mirapoint, Inc, for pointing these problems out and offering a
solution.

NOTE: We must put ed_probe_SIC() function into if_ed_isa.c because
this is a bus dependent code. But the ed driver code is not
separated explicitly whether it is bus dependent or independent
now.

- Make multicast work
- Fix (some of) the watchdog timeouts after card reset
- Add support for CE2, CEM28 and CEM33 cards
- General code cleanup
Any card that worked previously should still work, as well as a lot that
didn't.
The driver is not yet style(9) compliant; those changes are forthcoming,
once the functional changes are done.

timeout would continue to happen: boom! Fix this[*] by timing out earlier.
[*] almost fixes the race on unload: wi_inquire could be running when
untimeout is called, and there's no way to know when it has actually
returned. This race is very rare and hard to lose.

useful
o deal with entry to ath_ioctl during detach to disable promiscuous

the device is marked invalid as the code isn't prepared to deal
with it (in particular by that time the hal reference may have
been yanked)
