relying on what the register defaults are.
This forces the blink mode to be proportional to the TX and RX frames
which match the RX filter.
This (along with a few tweaks to if_ath_led.c to configure the correct
GPIO pins) allows my DWA-552 AR5416 NIC to blink the LEDs in a useful
fashion, however those LEDs are marked "Link" and "Act(ivity)", which
don't really map well to the "power" / "network" LED interface which
the MAC provides. Some further tinkering is needed to see what other
useful operating modes are possible.
Even though these header files make little sense to me, they are part of
the standard. By including these header files, you can simply use
`alignas', `alignof' and `noreturn' instead of the underscore-prefixed
versions.

sysclock_getsnapshot() function allows the caller to obtain a snapshot of all
the system clock and timecounter state required to create time stamps at a later
point. The sysclock_snap2bintime() function converts a previously obtained
snapshot into a bintime time stamp according to the specified flags e.g. which
system clock, uptime vs absolute time, etc.
These KPIs enable useful functionality, including direct comparison of the
feedback and feed-forward system clocks and generation of multiple time stamps
with different formats from a single timecounter read.

MS_SYNC flag. The system must guarantee that all writes are finished
before syscalls returned. Schedule the writes in async mode, which is
much faster and allows the clustering to occur. Wait for writes using
VOP_FSYNC(), since we are syncing the whole file mapping.
Potentially, the restriction to only apply the optimization can be
relaxed by not requiring that the mapping cover whole file, as it is
done by other OSes.

The reference driver directly enables/disables the LED state as required,
rather than nailing it up like it currently is. That'll have to come
later by adding some further HAL methods.

* Bring the AR5416 GPIO mux mask code in line with the code from the
HAL.
* Add HAL_DEBUG_GPIO debugging statements, to track what's going on.
* Add Kiwi GPIO specific changes for reading values back.
Obtained from: Atheros
* As a preparation for AR9287 GPIO support, add in the AR9287 GPIO mask.
* Fix the association mask values; these are post-shift values but were
being shifted in twice. This resulted in some garbage being written
in the wrong place and the link LED (at least on my d-link AR5416
NIC) giving totally incorrect blink patterns.
Some users were reporting concurrent resets _were_ occuring - ie,
either two ath_reset()s ran at the same time (likely one on each CPU)
or ath_reset() versus ath_chan_change().
Instead, this now tries to grab the serialisation semaphore and will
pause() for a while if it fails. It will always eventually succeed though
and will log an error if it hits the recursion situation.
All of this stuff needs to die a horrible death at some point and be
replaced with a properly serialising method of programming this stuff
(eg using the net80211 taskqueue for all of this stuff.) The trouble
is figuring out how to handle the concurrent ioctl() based things without
introducing more LORs (which is another reason why I haven't just wrapped
all of this stuff in large, long-lived locks, a-la what Linux can get
away with.)
