Here's my suggestion how to implement beacon filtering in mac80211.
The basic idea is simple, the driver enables filtering is whenever
mac80211 enables power save. Driver calls ieee80211_beacon_loss()
whenever hardware informs about beacon loss.
I have tested this with stlc45xx and based on simple tests this seems
to work. For reference I'll send stlc45xx patch as a followup.
TODO:
o API documentation
o test with different hardwares (without beacon filtering) to
avoid regressions

mac80211: add beacon filtering support
mac80211: track beacons separately from the rx path activity
mac80211: decrease execution of the associated timer
