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.

We can remove the STATE_RADIO_RX_ON_LINK and

 * move temp. ampdu_[ack]_len out of txinfo->pad.

 * fix WARN_ON from tx.c:line 300 when tx_ampdu_queue
   fails to queue the frame.

 * In tx_prepare, we already have a local pointer

crypto_free_cipher() is a wrapper around crypto_free_tfm() which is a
wrapper around crypto_destroy_tfm() and the latter can handle being passed
a NULL pointer, so checking for NULL in the
ieee80211_aes_key_free()/ieee80211_aes_cmac_key_free() wrappers around
crypto_free_cipher() is pointless and just increase object code size
needlesly and makes us execute extra test/branch instructions that we
don't need.
Btw; don't we have to many wrappers around wrappers ad nauseam here?
Anyway, this patch removes the redundant conditionals.

The BSSID register shouldn't be set in AP mode on some older devices (like
rt73usb) as it breaks hw crypto on these. However, rt2800 devices explicitly
need the BSSID register set to the same value as our own MAC address (only
in AP mode).

Hence, don't set the BSSID from rt2x00lib but move it down into rt2800 to
avoid problems on older devices.

This fixes a regression (at least for rt73usb) and avoids a new regression
for rt2800 devices in 2.6.36.

Implement a basic flush callback function, which simply loops
over all TX queues and waits until all frames have been transmitted
and the status reports have been gathered.

At this moment we don't support dropping any frames during the
flush, but mac80211 will only send 'false' for this argument anyway,
so this is not important at this time.
