From: Marty Faltesek <mfaltesek@xxxxxxxxxx> In uap mode the carrier is not enabled until after the first STA joins. The carrier triggers the bridge to start its state machine, and if STP is enabled, it takes 4 seconds as it transitions from disabled to forwarding. During this time the bridge drops all traffic, and the EAPOL handshake times out after 3 seconds, preventing stations from joining. Follow the logic used in mac80211 and start the carrier in start_ap and disable it in stop_ap. This has a nice benefit of allowing the first station connection time to be reduced by up to 75% when STP is in use.
