Subject: [PATCH] * Add a new capability which returns whether the hardware
 supports   the MYBEACON RX filter (only receive beacons which match the
 BSSID)   or all beacons on the current channel.

* Add the relevant RX filter entry for MYBEACON.

Tested:

* AR5416, STA
* AR9285, STA

TODO:

* once the code is in -HEAD, just make sure that the code which uses it
  correctly sets BEACON for pre-AR5416 chips.
