[RFC PATCH v2 0/4] mac80211: beacon filtering

[Kalle Valo <kalle.valo@nokia.com>]

Here's my proposal how to implement beacon filtering in mac80211. The
basic idea is simple, the driver enables filtering whenever mac80211
enables power save and the 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 earlier sent stlc45xx patch to this list.

v2:
o rebase to 2.6.29-rc7-wl
o rename ieee80211_rx_trigger() to ieee80211_sta_rx_notify()
o move check for sta mode in ieee80211_sta_rx_notify() to rx.c
o move unicast check from rx.c to ieee80211_sta_rx_notify()
o add comment for setting last_beacon in ieee80211_rx_mgmt_assoc_resp()
o rename IEEE80211_HW_BEACON_FILTERING to IEEE80211_HW_BEACON_FILTER
o send probe request from ieee80211_beacon_loss_work()
o API documentation
o enable beacon filtering only when power save is enabled
o disable power save (and hence beacon filtering) while scanning to make 
  it possible to have reliable scan results even when beacon filtering
  is enabled

TODO: 

o test with different hardware (without beacon filtering) to 
  avoid regressions

Kalle Valo (4):
      mac80211: add beacon filtering support
      mac80211: disable power save when scanning
      mac80211: track beacons separately from the rx path activity
      mac80211: decrease execution of the associated timer
