The NIC should send an event to the driverinforming about the low
signal strength situation and driver will forward this information to
mac80211. The firmware has knowledge of the beacon rssi so this should
be trivial to implement in firmware. But if the firmware really
doesn't support this, the driver can always disable beacon filtering
feature in mac80211.
