get it out of a stuck condition that can be caused by GEM_MAC_RX_OVERFLOW.
- 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
consistently use the newly introduced sc_mac_rxcfg throughout the driver
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
so developers who wish to test the net80211 DFS code can easily

DFS and thus the DFS stuff doesn't run.

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.

to do about the few cases where the HAL state isn't available (regdomain)
or isn't yet setup (probe/attach.)
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.
rather than global variables.
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.

resource allocation from an x86 Host-PCI bridge driver so that it can be
reused by the ACPI Host-PCI bridge driver (and eventually the MPTable
Host-PCI bridge driver) instead of duplicating the same logic. Note that
this means that hw.acpi.host_mem_start is now replaced with the
hw.pci.host_mem_start tunable that was already used in the non-ACPI case.
This also removes hw.acpi.host_mem_start on ia64 where it was not
applicable (the implementation was very x86-specific).
While here, adjust the logic to apply the new start address on any
"wildcard" allocation even if that allocation comes from a subset of
the allowable address range.

Implement checking valid link in state change callback and poll
active link state in vr_tick(). This allows immediate detection of
lost link as well as protecting driver from frequent link flips during
link renegotiation. taskq implementation was removed because driver
now needs to poll link state in vr_tick().
While I'm here do not report current link state if interface is not
