mac80211: refactor station state transitions
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. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: John W.
