different interface types, and for supporting asynchronous
firmware loading.

Certain firmware versions, particularly the 8388 found on the XO-1,
do not support the EHS_REMOVE_WAKEUP command that is used to disable
WOL. Sending this command to the card will return a failure that
would get propagated up the stack and cause suspend to fail.

Instead, fall back to an all-zero wakeup mask.

This hunk added by commit 66fceb69 seems erroneous. We don't want to
prevent suspend of the whole system if no wakeup params are set.

In the case of the usb8388 we do want to keep the card powered up even
if there are no wakeup params. This is because it will continue acting
as a mesh node.

If the mesh is disabled, it would indeed make more sense to power down
the card during suspend, as the equivalent hunk does for the SD interface.
But that's a separate task; for now just restore the previous behaviour.

The RXON rework resulted in a massive loss of
throughput because we weren't programming the
device completely correctly -- the BSSID has
to be programmed into the device before the
AP station is uploaded. To fix this, simply
always send the unassoc RXON, i.e. even when
it was already unassoc so that the BSSID and
some other parameters are updated properly.

"mac80211: Fix WMM driver queue configuration"
inadvertedly broke iwlwifi, because now mac80211
configures the QoS settings before assoc, and
therefore before HT. Thus, iwlwifi no longer told
the device about the HT setting, which it needs
to -- and thus throughput went down a lot. Fix
this by resending the QoS command to the device
not only when QoS/WMM settings change, but also
when HT changes.

Add watchdog functions for managing the Queues inside the hardware.
Normally the driver doesn't have much to do with these queues
directly, but the Ralink drivers did implement watchdog functions
for these. These watchdog functions are not triggered that often,
compared to the other watchdog functions, but I have at least
seen them trigger once or twice during a long stresstest run.
