Changes since v1:
* Clarify an unclear comment
* Move a (possible) name change to a separate patch
The ad_rx_machine, ad_periodic_machine and ad_port_selection_logic
functions all inspect and alter common fields within the port structure.
Previous to this patch, only the ad_rx_machines were mutexed, and the
periodic and port_selection could run unmutexed against an ad_rx_machine
trigged by an arriving LACPDU.
This patch remedies the situation by protecting all the state machines
from concurrency. This is accomplished by locking around all the state
machines for a given port, which are executed at regular intervals; and
the ad_rx_machine when handling an incoming LACPDU.

Usually H/W generate statistics notify once per about 100ms, but
sometimes we can receive notify in shorter time, even 2 ms.
This can be problem for plcp health and ack health checking.
I.e. with 2 plcp errors happens randomly in 2 ms duration, we
exceed plcp delta threshold equal to 100 (2*100/2).
Also checking ack's in short time, can results not necessary false
positive and firmware reset, for example when channel is noised and
we do not receive ACKs frames or when remote device does not send
ACKs at the moment.
Patch change code to do statistic check and possible recovery only
if 99ms elapsed from last check. Forced delay should assure we have
good statistic data to estimate hardware state.

The ATIM queue is considered to be a TX queue by the drivers that support
the queue. Therefore include support for the ATIM queue to the

Add the support in such a way that drivers that do not support the ATIM

When setting up multiple BSSIDs in AP mode on an rt2800pci device we
previously used the STAs AID to select an appropriate key slot. But
since the AID is per VIF we can end up with two STAs having the same AID
and thus using the same key index. This resulted in one STA overwriting
the key information of another STA.
Fix this by simply searching for the next unused entry in the pairwise
key table.
Also bring the key table init in sync with deleting keys by initializing
the key table entries to 0 instead of 1.

ieee80211_get_tx_rate is not valid for HT rates. Hence, restructure the
TX desciptor creation to be aware of MCS rates. The generic TX desciptor
creation now cares about the rate_mode (CCK, OFDM, MCS, GF).
As a result, ieee80211_get_tx_rate gets only called for legacy rates.
