  An alternative would be to send an EAP-Message containing a NAK
containing no data.

  i.e. 0x02000403

  It's EAP-Message, which satisfies the existing requirements.  An
intermediate proxy shouldn't really be snooping on the EAP conversation,
so it shouldn't care about the contents of EAP-Message.

  Anyone else looking at the contents should be clear that it's not a
working EAP session.
