Now the interface's bssid is reset upon ifdown. ieee80211_sta_find_ibss: if (found && memcmp(ifsta->bssid, bssid, ETH_ALEN) != 0 && (bss = ieee80211_rx_bss_get(dev, bssid, local->hw.conf.channel->center_freq, ifsta->ssid, ifsta->ssid_len))) Note: In general disconnection is still not handled properly in mac80211 Signed-off-by: Assaf Krauss Signed-off-by: Tomas Winkler Signed-off-by: John W.
