hostapd needs to know about the bridge/ovs interface to register a
PF_PACKET socket for EAPOL frames.
Otherwise hostapd opens a socket on wlanX but since EAPOL frames are
data frames they end up being bridged and hostapd never receives them.

I'm using the patch referenced in my previous email but it is more of
a hack then a clean patch ...
