ath9k: fix retry count for A-MPDU rate control status reports
The 'bf_retries' field of the ath_buf structure was used for both
software retries (AMPDU subframes) and hardware retries (legacy
frames). This led to a wrong retry count being reported for the A-MPDU
rate control stats.
This patch changes the code to no longer use bf_retries for reporting
retry counts, but instead always using the real on-chip retry count
from the ath_tx_status.
Additionally, if the first subframe of an A-MPDU was not acked, the tx
status report is submitted along with the first acked subframe, which
may not contain the correct rates in the tx info.
This is easily corrected by saving the tx rate info before looping over
subframes, and then copying it back once the A-MPDU status report is
submitted.
In my tests this change improves throughput visibly.

iwlwifi: apply filter flags directly
broke multicast. The reason, it turns out, is that
the code previously checked if ALLMULTI _changed_,
which the new code no longer did, and normally it
_never_ changes. Had somebody changed it manually,
the code prior to my patch there would have been
broken already.
The reason is that we always, unconditionally, ask
the device to pass up all multicast frames, but the
new code made it depend on ALLMULTI which broke it
since now we'd pass up multicast frames depending
on the default filter in the device, which isn't
necessarily what we want (since we don't program it
right now).
Fix this by simply not checking allmulti as we have
allmulti behaviour enabled already anyway.

mac80211: Add interface for driver to temporarily disable dynamic ps
This mechanism introduced in this patch applies (at least) for hardware
designs using a single shared antenna for both WLAN and BT. In these designs,
the antenna must be toggled between WLAN and BT.
In those hardware, managing WLAN co-existence with Bluetooth requires WLAN
full power save whenever there is Bluetooth activity in order for WLAN to be
able to periodically relinquish the antenna to be used for BT. This is because
BT can only access the shared antenna when WLAN is idle or asleep.
Some hardware, for instance the wl1271, are able to indicate to the host
whenever there is BT traffic. In essence, the hardware will send an indication
to the host whenever there is, for example, SCO traffic or A2DP traffic, and
will send another indication when the traffic is over.
The hardware gets information of Bluetooth traffic via hardware co-existence
control lines - these lines are used to negotiate the shared antenna
ownership. The hardware will give the antenna to BT whenever WLAN is sleeping.
This patch adds the interface to mac80211 to facilitate temporarily disabling
of dynamic power save as per request of the WLAN driver. This interface will
immediately force WLAN to full powersave, hence allowing BT coexistence as
described above.
In these kind of shared antenna desings, when WLAN powersave is fully disabled,
Bluetooth will not work simultaneously with WLAN at all. This patch does not
address that problem. This interface will not change PSM state, so if PSM is
disabled it will remain so. Solving this problem requires knowledge about BT
state, and is best done in user-space.

ath5k: review RX descriptor functions
Reviewed RX descriptor functions against the HAL sources. Some minor changes:
- check size before making changes to the descriptor
- whitespace
- add comments about 5210 timestamps. this needs to be adressed later!
- FIFO overrun error only available on 5210
- rs_phyerr should not be OR'ed
- clear the whole ath5k_rx_status structure before using, instead of
zeroing specific fields.
