Hmm.. So are you trying to get one of those ports authenticated to an
external switch port using IEEE 802.1X? I would be kind of interesting
in the other end of the authentication for wired networks, i.e., getting
hostapd authenticator running on a low-cost device that can do proper
port blocking.. Any idea whether that would work with those devices?

Is the management interface a normal netdev? If yes, you might be able
to use the -b option to specify it as a "bridge" interface. This would
allow EAPOL packets to be received from another interface.
