    Subject[ 05/83] mac80211: dont send null data packet when not associated
    Date
    3.6-stable review patch.  If anyone has any objections, please let me know.

    ------------------

    From: Johannes Berg <johannes.berg@intel.com>

    commit 20f544eea03db4b498942558b882d463ce575c3e upstream.

    On resume or firmware recovery, mac80211 sends a null
    data packet to see if the AP is still around and hasn't
    disconnected us. However, it always does this even if
    it wasn't even connected before, leading to a warning
    in the new channel context code. Fix this by checking
    that it's associated.
