rt2x00: Improve TX status handling for BlockAckReq frames
Since rt2800 hardware isn't capable of reporting the TX status of
BlockAckReq frames implement the TX status handling of BARs in
rt2x00lib. We keep track of all BARs that are send out and try to
match incoming BAs to the appropriate BARs. This allows us to report a
more or less accurate TX status for BAR frames which in turn improves
BA session stability.
This is loosley based on Christian Lamparter's patch for carl9170
"carl9170: fix HT peer BA session corruption".
We have to walk the list of pending BARs for every rx'red BA even
though most BAs don't belong to any of these BARs as they are just
acknowledging an AMPDU. To keep that overhead low use RCU which allows
us to walk the list of pending BARs without the need to acquire a lock.
This however requires us to _copy_ relevant information from the BAR
(RA, TA, control field, start sequence number) into our BAR list entry.

nl80211: allow user-space to set address for P2P_DEVICE
As per email discussion Jouni Malinen pointed out that:
"P2P message exchanges can be executed on the current operating channel
of any operation (both P2P and non-P2P station). These can be on 5 GHz
and even on 60 GHz (so yes, you _can_ do GO Negotiation on 60 GHz).
As an example, it would be possible to receive a GO Negotiation Request
frame on a 5 GHz only radio and then to complete GO Negotiation on that
band. This can happen both when connected to a P2P group (through client
discoverability mechanism) and when connected to a legacy AP (assuming
the station receive Probe Request frame from full scan in the beginning
of P2P device discovery)."
This means that P2P messages can be sent over different radio devices.
However, these should use the same P2P device address so it should be
able to provision this from user-space. This patch adds a parameter for
this to struct vif_params which should only be used during creation of
the P2P device interface.

mac80211: Optimize scans on current operating channel.
we do not disable PS while going back to operational channel (on
ieee80211_scan_state_suspend) and deffer that until scan finish.
But since we are allowed to send frames, we can send a frame to AP
without PM bit set, so disable PS on AP side. Then when we switch
to off-channel (in ieee80211_scan_state_resume) we do not enable PS.
Hence we are off-channel with PS disabled, frames are not buffered
by AP.
To fix remove offchannel_ps_disable argument and always enable PS when
going off-channel and disable it when going on-channel, like it was
before.

iwlwifi: audit single frames from AGG queue in RS
The rate scaling won't treat the information in a frame
with IEEE80211_TX_CTL_AMPDU set if IEEE80211_TX_STAT_AMPDU
is cleared. But all the frames coming from an AGG tx queue
have IEEE80211_TX_CTL_AMPDU set, and IEEE80211_TX_STAT_AMPDU
is set only if the frame was sent in an AMPDU.
This means that all the data in frames in AGG tx queues that
aren't sent as an AMPDU is thrown away.
This is even more harmful when in bad link conditions, the
frames are sent in an AMPDU and then finally sent as single
frame. So a lot of failures weren't reported and the rate
scaling got stuck in high rates leading to very poor
connectivity.
Fix that by clearing IEEE80211_TX_CTL_AMPDU when the frame
isn't part of an AMPDU.

mac80211_hwsim: fix beacon timestamp and mactime
Set the beacon timestamp once during "transmission" so the
monitor interface also gets a timestamped beacon.
Also use a common base between TX timestamp and RX
mactime. This eliminates "TX" path delay, which shows up
as a constant error in Toffset.
Get the global TSF once before iterating over all RX HWs,
so they all set a mactime with the same time base.

drivers/nfc/nfcwilink.c: use devm_kzalloc
devm_kzalloc allocates memory that is released when a driver detaches.
This patch uses devm_kzalloc for data that is allocated in the probe
function of a platform device and is only freed in the remove function.

brcmsmac: increase timer reference count for new timers only
On hardware reintialization reference count of
already existing timers would be increased again.
This leads to problems on module unloading.

ath9k: fix rx flush handling
Right now the rx flush is not doing anything useful on AR9003+, as it only
works if the buffers in the rx FIFO have not been purged yet, as is done
by ath_stoprecv.
To fix this, always call ath_flushrecv from within ath_stoprecv before
the FIFO is emptied, but still after the hw receive path has been stopped.
This ensures that frames received (and ACKed by the hardware) shortly before
a reset will be seen by the software, which should improve A-MPDU session
stability.

ath9k: add a better fix for the rx tasklet vs rx flush race
Ensure that the rx tasklet is no longer running when entering the reset path.
Also remove the distinction between flush and no-flush frame processing.
If a frame has been received and ACKed by the hardware, the stack needs to see
it, so that the BA receive window does not go out of sync.

During teardown, mac80211 will not return a new beacon. This is normal and

ath9k: fix double-free bug on beacon generate failure
When the next beacon is sent, the ath_buf from the previous run is reused.
If getting a new beacon from mac80211 fails, bf->bf_mpdu is not reset, yet
the skb is freed, leading to a double-free on the next beacon tx attempt,
resulting in a system crash.

On AR9300 the rx FIFO needs to be empty during reset to ensure that no
