+ * DOC: Beacon filter support

+ * Some hardware have beacon filter support to reduce host cpu wakeups

+ * changing elements (TSF, TIM etc). Whenever the checksum changes the

+ * way the host will only receive beacons where some relevant information
+ * (for example ERP protection or WMM settings) have changed.
