The problem with PSM when a hidden SSID was used was originally
reported by Juuso Oikarinen.
- When generally scanning, the AP is getting a bss entry with
a zero SSID.
- When associating, a probe-req is sent to the AP with the SSID,
and as a result a probe-response is received with the hidden
SSID in place. As a consequence, a second bss entry is created
for the AP, now with the real SSID.
- After association, mac80211 executes ieee80211_recalc_ps(),
but does not switch to powersave because the beacon-ies are missing.
As result, the STA does not ever enter PSM.
The patch merges in beacon ies of hidden bss from beacon to the probe
response, creating a consistent set of ies in place.
Patch is depended on "cfg80211: fix cmp_ies" made by Johannes.

net: add wireless TX status socket option
The 802.1X EAPOL handshake hostapd does requires
knowing whether the frame was ack'ed by the peer.
Currently, we fudge this pretty badly by not even
transmitting the frame as a normal data frame but
injecting it with radiotap and getting the status
out of radiotap monitor as well. This is rather
complex, confuses users (mon.wlan0 presence) and
doesn't work with all hardware.
To get rid of that hack, introduce a real wifi TX
status option for data frame transmissions.
This works similar to the existing TX timestamping
in that it reflects the SKB back to the socket's
error queue with a SCM_WIFI_STATUS cmsg that has
an int indicating ACK status (0/1).
Since it is possible that at some point we will
want to have TX timestamping and wifi status in a
single errqueue SKB (there's little point in not
doing that), redefine SO_EE_ORIGIN_TIMESTAMPING
to SO_EE_ORIGIN_TXSTATUS which can collect more
than just the timestamp; keep the old constant
as an alias of course. Currently the internal APIs
don't make that possible, but it wouldn't be hard
to split them up in a way that makes it possible.

Bluetooth: Pass full hci_dev struct to mgmt callbacks
The current global pending command list in mgmt.c is racy. Possibly the
simplest way to fix it is to have per-hci dev lists instead of a global
one (all commands that need a pending struct are hci_dev specific).
This way the list can be protected using the already existing per-hci
dev lock. To enable this refactoring the first thing that needs to be
done is to ensure that the mgmt functions have access to the hci_dev
struct (instead of just the dev id).

ath9k: Add btcoex profile management support for AR9462
AR9462 chips have the capabilities to provoide bluetooth
profile information. For non-AR9462 btcoex chips, the BT
priority traffic was identified by periodically polling
the respective registers and updated dutycycle, stomptype,
etc. As AR9462 chip offers the BT profile informations,
let us make use of that to update aggregation limit,
dutycycle, stomptype and wieghtages.

mac80211: support adding IV-room in the skb for CCMP keys
Some cards can generate CCMP IVs in HW, but require the space for the IV
to be pre-allocated in the frame at the correct offset. Add a key flag
that allows us to achieve this.

brcm80211: smac: change buffer endianess convert function interface
The buffer endianess conversion functions in srom.c had a size
argument giving number of bytes but the function converts words.
Providing the number of words to the function is more sensible
so that is done in this patch.
