Do you know what kind of port control features are available in the
switch driver? For example, can it be configured to allow EAPOL frames
(separate ethertype) and drop all other packets?

Wired driver interface should be a good starting point. If the switch
driver has support for some level of port control, the wired driver
would be extended to configure the driver to open/close the port based
on authentication state.
