I noticed a simmilar problem with the wired driver.  The senario is like
this:

* the wired supplicant connected to a cisco switch
* wpa_supplicant is started and authenticates
* the switch opens the port
* now I take the supplicant plug out from the switch port
* wait a second and plug it back in
* the switch sends a EAP-Request (as it is supposed to)
* the supplicant can't mannage to reauthenticate

Shouldn't be difficult to reproduce in another environment, but I can
provide the debug log/trace if required.


Cheers,
Cristian
