change a per-instance variable (which is used to control AIM) rather
than having all of the per-instance sysctls operate on a single global

the AP doesn't transmit beacons.
If the AP requests a CSA (ie, a channel switch) and then enters CAC
(channel availability check) for 60 seconds, it doesn't send beacons
and it just listens for radar events (and other things which we don't
do yet.)
Now, ath_newstate() was not resetting the beacon timer config on
a transition to the RUN state when in STA mode - it was setting
sc_syncbeacon, which simply updates the beacon config from the
contents of the next received beacon.
This means the STA never generates beacon miss events.
If the AP goes into CAC for 60 seconds and recovers, the STA will
happily receive the first beacon and reconfigure timers.
But if it gets a radar event after that, it'll change channel
again, not notify the station that it's changed channel..
and since the station is happily waiting for the first beacon
to configure the beacon timer details from, it won't ever
generate a beacon miss interrupt and it'll sit there forever
(or until the AP appears on that channel once again.)
This change forces the last known beacon timer config to be
written to hardware on a transition from CSA->RUN in STA mode.
This forces bmiss events to occur and the STA will eventually
(after a handful of beacon miss events) begin scanning for
another access point.

- In gem_reset_rxdma() call gem_setladrf() in order to reprogram the RX
filter and restore the previous content of GEM_MAC_RX_CONFIG. While at it

instead of reading the its old content.
- Increment if_iqdrops instead of if_ierrors in case of RX buffer allocation
failure.
- According to the GEM datasheet the RX MAC should also be disabled in
gem_setladrf() before changing its configuration.
- Add error messages to gem_disable_{r,t}x() and take advantage of these
throughout the driver instead of duplicating their functionality all over
the place.

The DFS code was tickling the channel set directly whilst going
through the state RUN -> CSA -> RUN. This only changed the channel;
it didn't go via ath_reset(). However in this driver, a channel
change always causes a chip reset, which resets the beacon timer
configuration and interrupt setup. This meant that data would go
out but as the beacon timers never fired, beacons would never
be queued.
The confusing part is that sometimes the state transition was
RUN -> SCAN -> CAC -> RUN (with CSA being in there sometimes);
going via SCAN would clear sc_beacons and thus the transition
to RUN would reprogram beacon transmission.
In case someone tries debugging why suspending a device currently
beaconing (versus just RX'ing beacons which is what occurs in STA
mode), add a silly comment which should hopefully land them at
this commit message. The call to ath_hal_reset() will be clearing
the beacon config and it may not be always reset.

This doesn't at all actually do radar detection! It's just

It appears that the addition to uath(4) came in through PR kern/135009,
which had tested another device, the SMCWUSBTG2, successfully with uath(4)
and included the SMCWUSBG as it "has the same chipset". I can find no
other evidence that these two do actually share the same chipset. Moreover,
Linux treats the SMCWUSBG as a zyd(4) device also.

The global ath_hal_debug now affects all instances of the HAL.
This also restores the ability for probe/attach debugging to work; as
the sysctl tree may not be attached at that point. Users can just set
the global "hw.ath.hal.debug" to a suitable value to enable probe/attach
related debugging.

This specifically allows for debugging to be enabled per-NIC, rather
than globally.
Since the ath driver doesn't know about AH_DEBUG, and to keep the ABI
consistent regardless of whether AH_DEBUG is enabled or not, enable the
debug parameter always but only conditionally compile in the debug
methods if needed.
The ALQ support is currently still global pending some brainstorming.
