+Subject: [PATCH 06/15] wl12xx: Unset bssid filter, ssid and bssid from firmware on disassoc
+
+On the disassociation event from the mac80211, the wl12xx driver does not
+clear the chipset configuration related to the AP - i.e. it does not perform
+a DISCONNECT and then a JOIN with zero SSID and dummy BSSID. Also, it does not
+unset the BSSID filter.
+
+Often this is not a problem, as the above is performed upon entering idle
+state. But if a scenario arises where a new association is attempted without
+cycling through idle state, the new association will fail.
+
+Fix this by resetting the firmware state on disassociation.
