The wl12xx device normally drops all frames coming from BSSID it is not joined with. This behavior is configured today by the wl12xx driver in response to a handful of ieee80211_bss_change and ieee80211_conf_changed notification flags, such as BSS_CHANGED_ASSOC, BSS_CHANGED_BSSID, IEEE80211_CONF_CHANGE_IDLE, etc.. This breaks when we roam to a new BSSID, where authentication frames are sent before any BSS_CHANGED/CONF_CHANGED flags are received. When this happens the hardware silently drops the authentication responses, and the roaming fails. Ideally this aggressive filtering behavior of the device should be disabled upon a notification from mac80211. Such notification will take place after multi-channel support will be added: mac80211 will likely send a remain-on-channel notification to drivers when entering sensitive states (like authentication), otherwise the firmware might jump to different channels (to serve a different role). Until those notifications materialize, disable the hw BSSID filter when authentication requests are sent, so roaming would work.
