- When trying to re-route interrupts, don't change cfg->intline if the
re-route fails by returning an invalid vector. This fixes machines
without any way of routing interrupts such as older PC's without a
$PIR table.
We do not currently write the new intline value back to the hardware, but
we should. That will likely be added in a later commit.
if it was already enabled. We don't want to set it
when it shouldn't be set, we just don't want to
inadvertantly turn it off. This should fix a recent
report of the aic7xxx driver repeatedly complaining of
"unexpected busfree while idle" in one configuration.
successfully mapping our registers. This
avoids the disabling of memory mapped I/O
just because some other driver probe happened
to touch our registers.
This drive delays going async after receiving a WDTR
message. We now send an SDTR message after a WDTR even
if our goal is to go async. This should work even for
confused devices.
If we get an unexpected busfree when attempting a WDTR
or SDTR, only set the goal negotiation parameters we were
trying to negotiate to off. This means that should a WDTR
message fail, we will still try an SDTR if our goal is
non-async.
Fix a few more places where we were looking at goal.period
instead of goal.offset for determining if we should be
negotiating sync. This should not have any impact on
our behavior, but the offset is more definitive and should
be used.

Switch ah?_reset() to take an additional "reinit" argument.
Use this instead of init_level to determin if the chip
should be fully reinitialized after a chip reset. This
is required so that ah?_shutdown() can reset the chip
without side-effects.

Implement ahd_suspend() and ahd_resume().

Change ahc_loadseq() to *not* restart the sequencer.
This brings the loadseq behavior in line with that
of the 7902 driver and also simplifies the init routine.
Correct the resume routine to enable interrupts and
restart the sequencer.
obtained from o2micro. These should only be needed for 'older'
o2micro bridges (anything before the 7xxx series of bridges), but will
work with the new bridges.

Add sysctl's to display statistics/debug_info
Set WAIT_FOR_AUTONEG_DEFAULT to zero by default
Increment packet in/out statistics inline instead of every two seconds.

Always route PCI interrupts on i386 UP machines. I was planning to enable
this for i386 anyways once SMP support is done. Having this enabled fixes
problems on many people's laptops.

While a string is readable without a tool, an array is easier to process for
a monitoring application. This also prevents the extra hoops we need with
sbufs and locking.
Move the mtx_init() in en_attach() higher before the first failure point so
that we can unconditionally destroy it in en_destroy().
to unload. This would cause a panic on the second resetconfig.
Start Vinum at boot time at SI_SUB_RAID, not SI_SUB_VINUM.
SI_SUB_VINUM was there first, but there's no real distinction, and
SI_SUB_RAID is a more neutral name.

o adding locking to op submission
o mark interrupt handler MPSAFE
o don't use locking on detach; disabling interrupts should be sufficient
o change mutex string names so witness printouts are more meaningful
Note: locking is still pretty brute-force but it's probably not worth
improving it given the relatively low performance of hifn-based cards.
o replace driver-global lock with three locks: one for the handling of mcr1
operations, one for handling of mcr2 operations, and one for the mcr1
free list
o mark the interrupt handler MPSAFE
o don't use locking on detach; disabling interrupts is sufficient (I think)
Change the list interface to simplify things.
Remove old list ioctls which bogusly exported the softc to userland.
Move the softc and associated structures from the public header to
the source file.
Make CCD a GEOM class.
For now only use this for implementing a OAM config method which
can return a list of configured CCD devices in the format which
"ccdconfig -g[v]" would normally output.
