    mac80211: free ifsta->extra_ie and clear IEEE80211_STA_PRIVACY_INVOKED · a10605e5

    I'm not sure if this is best choice, someone might have better
    solutions. But this patch fixed the connection problem when switching
    from a WPA enabled AP (using wpa_supplicant) to an open AP (using
    iwconfig). The root cause is when we connect to a WPA enabled AP,
    wpa_supplicant sets the ifsta->extra_ie thru SIOCSIWGENIE. But if we
    stop wpa_supplicant and connect to an open AP with iwconfig, there is
    no way to clear the extra_ie so that mac80211 keeps connecting with that.
    Someone could argue wpa_supplicant should clear the extra_ie during
    its shutdown. But mac80211 should also handle the unexpected shutdown
    case (ie. killall -9 wpa_supplicant).
