The updated patch here partially fixes the problem, the EAP packets will
be passed now.

The remaining issue is that when the wireless interface is added to the
trunk it will get a down/up as part of changing the MAC address. This
causes wpa_supplicant to close and it doesnt get relaunched. Manually
starting wpa_supplicant works but I need to find a way around this.
