ath9k: remove rssi/antenna information from recv debug stats
The way this is implemented (simply storing the last value) is absolutely
worthless for debugging anything, and the same information is also available
through the MAC sample feature, so there's no point in keeping this around.

This initial DFS module provides basic functionality to deal

ath9k: fix tx queue index confusion in debugfs code
Various places printing tx queue information used various different ways to
get a tx queue index for printing statistics. Most of these ways were wrong.
ATH_TXQ_AC_* cannot be used as an index for sc->tx.txq, because it is only
used internally for queue assignment.
One place used WME_AC_* as a queue index for sc->debug.stats.txstats, however
this array uses the ath9k_hw queue number as well.
Fix all of this by always using the ath9k_hw queue number as an index, and
always looking it up by going through sc->tx.txq_map.

ath9k: rework tx queue selection and fix queue stopping/waking
The current ath9k tx queue handling code showed a few issues that could
lead to locking issues, tx stalls due to stopped queues, and maybe even
DMA issues.
The main source of these issues is that in some places the queue is
selected via skb queue mapping in places where this mapping may no
longer be valid. One such place is when data frames are transmitted via
the CAB queue (for powersave buffered frames). This is made even worse
by a lookup WMM AC values from the assigned tx queue (which is
undefined for the CAB queue).
This messed up the pending frame counting, which in turn caused issues
with queues getting stopped, but not woken again.
To fix these issues, this patch removes an unnecessary abstraction
separating a driver internal queue number from the skb queue number
(not to be confused with the hardware queue number).
It seems that this abstraction may have been necessary because of tx
queue preinitialization from the initvals. This patch avoids breakage
here by pushing the software <-> hardware queue mapping to the function
that assigns the tx queues and redefining the WMM AC definitions to
match the numbers used by mac80211 (also affects ath9k_htc).
To ensure consistency wrt. pending frame count tracking, these counters
are moved to the ath_txq struct, updated with the txq lock held, but
only where the tx queue selected by the skb queue map actually matches
the tx queue used by the driver for the frame.

ath9k: Fix PS mode operation to receive buffered broadcast/multicast frames
The previous implementation was moving back to NETWORK SLEEP state
immediately after receiving a Beacon frame. This means that we are
unlikely to receive all the buffered broadcast/multicast frames that
would be sent after DTIM Beacon frames. Fix this by parsing the Beacon
frame and remaining awake, if needed, to receive the buffered
broadcast/multicast frames. The last buffered frame will trigger the
move back into NETWORK SLEEP state.
If the last broadcast/multicast frame is not received properly (or if
the AP fails to send it), the next Beacon frame will work as a backup
trigger for returning into NETWORK SLEEP.
A new debug type, PS (debug=0x800 module parameter), is added to make
it easier to debug potential power save issues in the
future. Currently, this is only used for the Beacon frame and buffered
broadcast/multicast receiving.
