+This patch fixes a bug in net80211/ieee80211_wireless.c preventing 
+the user from setting a certain BSSID by 
+"iwconfig athX ap XX:XX:XX:XX:XX:XX". 
+It furthermore prevents merging to another IBSS in ad-hoc mode 
+if a BSSID was set previously by the above command.
+It was tested with the snapshot madwifi-ng-r1696-20060730.
