    Subject[patch 02/43] mac80211: decrement ref count to netdev after launching mesh discovery
    2.6.28-stable review patch.  If anyone has any objections, please let us know.

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

    From: Brian Cavagnolo <brian@cozybit.com>

    commit 5dc306f3bd1d4cfdf79df39221b3036eab1ddcf3 upstream.

    After launching mesh discovery in tx path, reference count was not being
    decremented. This was preventing module unload.
