Jouni Malinen 9d1857cf35 Process Transition Disable KDE in station mode
Check whether the Transition Disable KDE is received from an
authenticated AP and if so, whether it contains valid indication for
disabling a transition mode. If that is the case, update the local
network profile by removing the less secure options.
