+ * Ideally, the hardware would filter out any beacons without changes in the

+ * Note that change, for the sake of simplification, also includes information
+ * elements appearing or disappearing from the beacon.

+ * it could also include some currently unused IDs.

+ * In addition to these capabilities, hardware should support notifying the

+ * when no traffic is flowing (when traffic is flowing we see the RSSI of
+ * the received data packets). This can consist in notifying the host when
+ * the RSSI changes significantly or when it drops below or rises above
+ * configurable thresholds. In the future these thresholds will also be
+ * configured by mac80211 (which gets them from userspace) to implement
