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.

ath9k: remove sc->rx.rxbuflock to fix a deadlock

The commit "ath9k: fix rx flush handling" added a deadlock that happens
because ath_rx_tasklet is called in a section that has already taken the
rx buffer lock.

It seems that the only purpose of the rxbuflock was a band-aid fix to the
reset vs rx tasklet race, which has been properly fixed in the commit
"ath9k: add a better fix for the rx tasklet vs rx flush race".

Now that the fix is in, we can safely remove the lock to avoid such issues.

NFC: Initial Secure Element API

Each NFC adapter can have several links to different secure elements and
that property needs to be exported by the drivers.
A secure element link can be enabled and disabled, and card emulation will
be handled by the currently active one. Otherwise card emulation will be
