  Blame the client.

  The client *should* send an EAP-NAK, and request PEAP.  I see this
when I use eapol_test, which is based on wpa_supplicant.

  In any case, RADIUS is driven by the client.  If the server sends a
packet and the client doesn't "respond", it means that the client has
decided to stop talking to the server.
