Sorry, I _had_ to fix the ieee80211_beacon_loss() interface ;)
Oh yeah, forgot to mention that I did some quick measurements and with
these patches I was able get 25% system power consumption decrease
with stlc45xx on Nokia N800 in the wlan idle case (associated to the
AP, no data traffic, display off). I'll do more measurements later.
