ieee80211_stop_rx_ba_session() was calling sta_info_get()
without rcu locking, and the return value was not
checked.
This resulted in the following panic:[] (ieee80211_stop_rx_ba_session+0x0/0x60 [mac80211])
[] (wl1271_event_handle+0x0/0xdc8 [wl12xx])

cfg80211_netdev_notifier_call() is configuring psm in case
of NL80211_IFTYPE_STATION interface type (on NETDEV_UP).

In P2P client mode, the GO (AP) to connect to might
have periods of time where it is not available due
to powersave. To allow the driver to sync with it
and send frames to the GO only when it is available
add a new callback tx_sync (and the corresponding
finish_tx_sync). These callbacks can sleep unlike
the actual TX.Signed-off-by: Johannes Berg

Both ath5k_hw and ath5k_softc represent one instance of the hardware.
This duplication is historical and is not needed anymore.Keep the name "ath5k_hw" for the merged structure and "ah" for the
variable pointing to it. "ath5k_hw" is shorter than "ath5k_softc", more
descriptive and more widely used.Put the combined structure to ath5k.h where the old ath5k_softc used to
be. Move some code from base.h to ath5k.h as needed.Remove memory allocation for struct ath5k_hw and the corresponding error
handling. Merge iobase and ah_iobase fields.Signed-off-by: Pavel Roskin

Some of the newer Broadcom chipsets have longe names like BCM43224,

them. Use %X or %d depending on chip_id value to avoid BCMA8D8, etc.Signed-off-by: Rafał Miłecki

Scanning currently uses the TX rate mask to
restrict the rate set, which is bogus. Make
it use the new set of rates from userspace.Signed-off-by: Johannes Berg
Signed-off-by: John W. Linville -
Some P2P scans are not allowed to advertise
11b rates, but that is a rather special case
so instead of having that, allow userspace
to request the rate sets (per band) that are
advertised in scan probe request frames.Since it's needed in two places now, factor
out some common code parsing a rate array.Signed-off-by: Johannes Berg

Harshal Chhaya discovered during network tests, that
several of his clients dropped-off the network. The
captured packets shows that the beacons sent by the
AP are at a much lower power than the other data
packets.The reason for this mishap: The driver never updated
the beacon phy register, so all beacons were always
sent at the lowest power.Reference: http://marc.info/?l=linux-wireless&m=131067225105801

Add tx_conf array to save the current tx queues
configuration, and reconfig it on resume (ieee80211_reconfig).On resume, the driver is being reconfigured. Without
reconfiguring the tx queues as well, the driver might
configure the device to use wrong ac params (e.g. ps-poll
instead of uapsd).Signed-off-by: Eliad Peller
