It's AR5416 and later specific; I'll add a HAL method to generalise it
later.

binmisc code to be build on amd64/i386 for the kernel.

Update NOTES with some indication of what this code is used for.

psuedo-PNP ISA devices.  (The ie(4) driver in FreeBSD/i386 is one
example.)

This patch adds support for three new SCSI commands: UNMAP, WRITE SAME(10)
and WRITE SAME(16).  WRITE SAME commands support both normal write mode
and UNMAP flag.  To properly report UNMAP capabilities this patch also adds
support for reporting two new VPD pages: Block limits and Logical Block
Provisioning.

UNMAP support can be enabled per-LUN by adding "-o unmap=on" to `ctladm
create` command line or "option unmap on" to lun sections of /etc/ctl.conf.

At this moment UNMAP supported for ramdisks and device-backed block LUNs.
It was tested to work great with ZFS ZVOLs.  For file-backed LUNs UNMAP
support is unfortunately missing due to absence of respective VFS KPI.

execution to a emumation program via parsing of ELF header information.

With this kernel module and userland tool, poudriere is able to build
ports packages via the QEMU userland tools (or another emulator program)
in a different architecture chroot, e.g. TARGET=mips TARGET_ARCH=mips

I'm not connecting this to GENERIC for obvious reasons, but this should
allow the kernel module to be built by default and enable the building
of the userland tool (which automatically loads the kernel module).

tracked BAW actually is.

The net80211 code that completes a BAR will set tid->txa_start (the
BAW start) to whatever value was called when sending the BAR.
Now, in case there's bugs in my driver code that cause the BAW
to slip along, we should make sure that the new BAW we start
at is actually what we currently have it at, not what we've sent.

This totally breaks the specification and so this stays a printf().
If it happens then I need to know and fix it.

Whilst here, add some debugging updates:

* add TID logging to places where it's useful;
* use SEQNO().

if we've hit the end of the list and cycled around to the first
node again.

match how it's used.

This is another bug that led to aggregate traffic hanging because
the BAW tracking stopped being accurate.  In this instance, a filtered
frame that exceeded retries would return a non-error, which would
mean the caller would never remove it from the BAW.  But it wouldn't
be added to the filtered list, so it would be lost forever.  There'd
thus be a hole in the BAW that would never get transmitted and
this leads to a traffic hang.

Tested:

* Routerstation Pro, AR9220 AP

we did suspend it.

The whole suspend/resume TID queue thing is supposed to be a matched
reference count - a subsystem (eg addba negotiation, BAR transmission,
filtered frames, etc) is supposed to call pause() once and then resume()
once.

ath_tx_tid_filt_comp_complete() is called upon the completion of any
filtered frame, regardless of whether the driver had aleady seen
a filtered frame and called pause().

So only call resume() if tid->isfiltered = 1, which indicates that
we had called pause() once.

This fixes a seemingly whacked and different problem - traffic hangs.

What was actually going on:

* There'd be some marginal link with crappy behaviour, causing filtered
  frames and BAR TXing to occur;
* A BAR TX would occur, setting the new BAW (block-ack window) to seqno n;
* .. and pause() would be called, blocking further transmission;
* A filtered frame completion would occur from the hardware, but with
  tid->isfiltered = 0 which indiciates we haven't actually marked
  the queue yet as filtered;
* ath_tx_tid_filt_comp_complete() would call resume(), continuing
  transmission;
* Some frames would be queued to the hardware, since the TID is now no
  longer paused;
* .. and if some make it out and ACked successfully, the new BAW
  may be seqno n+1 or more;
* .. then the BAR TX completes and sets the new seqno back to n.

At this point the BAW tracking would be loopy because the BAW
start was modified but the BAW ring buffer wasn't updated in lock
step.

Tested:

* Routerstation Pro + AR9220 AP

* Define support for the SDHCI driver, although it doesn't work yet
* Fix the memory mappings for IPU [1]

For now this'll match up with the "wakeups"; although I'll dig deeper into
this to see if we can determine which sleep state the CPU managed to get
into.  Most things I've seen these days only expose up to C2 or C3 via
ACPI even though the CPU goes all the way down to C6 or C7.
