Error checking for aggregation frames should go into aggregation queue,
if aggregation queue not available, use legacy queue instead.
Also make sure the aggregation queue is available to activate,
if driver and mac80211 is out-of-sync, try to disable the queue and
sync-up with mac80211.

Even if the null data frame is not acked by the AP, mac80211
goes into power save. This might lead to loss of frames
from the AP.

The current mac80211 implementation enables power save if there
is no Tx traffic for a specific timeout. Hence, PS is triggered
even if there is a continuous Rx only traffic(like UDP) going on.
This makes the drivers to wait on the tim bit in the next beacon
to awake which leads to redundant sleep-wake cycles.
Fix this by restarting the dynamic ps timer on receiving every
data packet.

When running directed active scans we currently end up sending both the SSID
probe requests and an additional broadcast one.
This is due to the fact that we always leave the probe request template SSID IE
length to 0. Instead we should set it to the first SSID to scan, and fill the
direct_scan array with the remaining SSIDs to scan for. This way we only send
what we've been asked to: a broadcast probe request when no directed scan is
requested, and directed probe requests otherwise.

Retrying commands seldomly works, most often the firmware is in a
weird state anyway and needs the device to reset. So it's better
to report the broken state back to user-space.

which better reflect it's usage.
