-support access to MII_ANER too for completeness
-remove some hacks which disappeared in FreeBSD if_rl.c
rev. 1.25 (Aug 31 14:45:49 1999)
(the driver could need more updating, but this is what I've tested
for months)
- cac_pci_l0 has been moved to cac.c, since it's useful for EISA boards.
- Model-specific linkage now is responsible for DMA synchronization.
- If we don't recognise the board, print the subsystem ID.
- Add support for RAID LC2 and Smart Array 431.
- Start firmware background tasks on controllers that need it.
- Pull in linkage useful for both PCI and EISA boards from cac_pci.c.
- cac_ccb_done() now frees the done CCB if the CCB callback completes.
- Model-specific linkage is now responsible for DMA synchronization.
- Use wakeup_one() in cac_ccb_free().
- Start synchronous commands `manually'.
- Add one hardware check in DIAGNOSTIC case.
- Improve error messages.
- Start firmware background tasks on controllers that need it.
'get pkg.tgz "| cd /var/tmp/inst ; gunzip | tar -x -f -"'), handle
two cases better:
1. Timing out ftp connections: Make sure the hanging pipeline gets a ^C
(SIGINT), and wait until the ftp prompt is available again. Else we
may nuke away tar's working dir, and it may be displeased.
2. One of the commands from the pipeline exiting: caught via SIGCHLD;
for this signal to be delivered, a empty handler is needed)

tsleep() instead of DELAY. Also, keep trying flushing buffers when the
number of dirty buffers decreases (20 rounds may not be enouth for a
very large buffer cache).
Using tsleep instead of delay gives a chance to others kernel threads to run,
which is needed for raidframe. With this change I've not been able to
reproduce the 'dirty buffer not flushed' problem with raidframe.
with the following modifications to the initial patch:
- rename SHOLD and P_HOST to SSUSPEND and P_SUSPEND to avoid confusion with
PHOLD()
- don't deal with SSUSPEND/P_SUSPEND in fork1(), if we come here while
scheduler is suspended we're forking proc0, which can't have P_SUSPEND set.
sched_suspend() suspends the scheduling of users process, by removing all
processes from the run queues and changing their state from SRUN to
SSUSPEND. Also mark all user process but curproc P_SUSPEND.
When a process has to be put in SRUN and is marked P_SUSPEND, it's placed in
the SSUSPEND state instead.
sched_resume() places all SSUSPEND processes back in SRUN, clear the P_SUSPEND
flag.
