to trip a bug causing the latter to return a zeroed struct
aac_adapter_info. This causes two issues. One is cosmetic only --
a verbose boot prints information about the controller, and shows all
zero:
aac0: Unknown processor 0MHz, 0MB memory (0MB cache, 0MB execution),
unknown battery platform
The second problem is that the firmware version information is stored
away for aac_rev_check, for userland tools (like aaccli) to query via
the FSACTL_MINIPORT_REV_CHECK and FSACTL_LNX_MINIPORT_REV_CHECK ioctls.
When aaccli encounters this issue it prints
Command Error: <The current AFAAPI.DLL is too old to work with the
current controller software.>
Move the RequestSupplementAdapterInfo call after RequestAdapterInfo,
which seems to fix both problems.
abstraction as the RAID and CAM modules, making it nearly impossible
for enough initialization to be done in time for the RAID module to
know whether to attach. On top of this, no reset was being done on
the controller on attach, in violation of the spec. Additionally,
the port enable step was being deferred to the end of the attach
process, long after it should have been done to ensure reliable
operation from the controller. Fix all of these with a few hacks
to force the "attach" and "enable" steps of the core module early
on, and ensure that a reset and port enable also happens early on.
In the future, the driver needs to be refactored to eliminate the
core module abstraction, clean up withe reset/enable steps, and
defer event messages until all of the modules are available to
recieve them.
offload bugs by manual padding for short IP/UDP frames. Unfortunately
it seems that these workaround does not work reliably on newer PCIe
variants of RealTek chips.
To workaround the hardware bug, always pad short frames if Tx IP
checksum offload is requested. It seems that the hardware has a
bug in IP checksum offload handling. NetBSD manually pads short
frames only when the length of IP frame is less than 28 bytes but I
chose 60 bytes to safety. Also unconditionally set IP checksum
offload bit in Tx descriptor if any TCP or UDP checksum offload is
requested. This is the same way as Linux does but it's not
mentioned in data sheet.

these days, so de-generalize the acquire_timer/release_timer api
to just deal with speakers.
The new (optional) MD functions are:
timer_spkr_acquire()
timer_spkr_release()
and
timer_spkr_setfreq()
the last of which configures the timer to generate a tone of a given
frequency, in Hz instead of 1/1193182th of seconds.
Drop entirely timer2 on pc98, it is not used anywhere at all.
Move sysbeep() to kern/tty_cons.c and use the timer_spkr*() if
they exist, and do nothing otherwise.
Remove prototypes and empty acquire-/release-timer() and sysbeep()
functions from the non-beeping archs.
This eliminate the need for the speaker driver to know about
i8254frequency at all. In theory this makes the speaker driver MI,
contingent on the timer_spkr_*() functions existing but the driver
does not know this yet and still attaches to the ISA bus.
Syscons is more tricky, in one function, sc_tone(), it knows the hz
and things are just fine.
In the other function, sc_bell() it seems to get the period from
the KDMKTONE ioctl in terms if 1/1193182th second, so we hardcode
the 1193182 and leave it at that. It's probably not important.
Change a few other sysbeep() uses which obviously knew that the
argument was in terms of i8254 frequency, and leave alone those
that look like people thought sysbeep() took frequency in hertz.
This eliminates the knowledge of i8254_freq from all but the actual
clock.c code and the prof_machdep.c on amd64 and i386, where I think
it would be smart to ask for help from the timecounters anyway [TBD].
Removed dead code that assumed that M_TRYWAIT can return NULL; it's not true
since the advent of MBUMA.

in the cache which the sync(BUS_DMASYNC_POSTREAD) in usb_transfer_complete

writes out of the cache before usb_transfer_complete is called.
This fixes USB on xscale and likely other places.
