    mac80211: refactor station state transitions · d9a7ddb0
    Johannes Berg authored
    Station entries can have various states, the most
    important ones being auth, assoc and authorized.
    This patch prepares us for telling the driver about
    these states, we don't want to confuse drivers with
    strange transitions, so with this we enforce that
    they move in the right order between them (back and
    forth); some transitions might happen before the
    driver even knows about the station, but at least
    runtime transitions will be ordered correctly.
    As a consequence, IBSS and MESH stations will now
    have the ASSOC flag set (so they can transition to
    AUTHORIZED), and we can get rid of a special case
    in TX processing.
    When freeing a station, unwind the state so that
    other parts of the code (or drivers later) can rely
    on the transitions.
