[PATCH] ipw2200: wireless extension sensitivity threshold support

The patch allows the user to set the handover threshold, i.e. the number
of consecutively missed beacons that will trigger a roaming attempt. The
disassociation threshold is set to 3 times the handover threshold.

+3.2 iwconfig sens
+-----------------------------------------------
+
+The 'iwconfig ethX sens XX' command will not set the signal sensitivity
+threshold, as described in iwconfig documentation, but rather the number
+of consecutive missed beacons that will trigger handover, i.e. roaming
+to another access point. At the same time, it will set the disassociation
+threshold to 3 times the given value.
