EAP-TNC: Add Flags field into fragment acknowledgement
TNC IF-T is somewhat unclear on this are, but draft-hanna-nea-pt-eap-00.txt, which is supposed to define the same protocol, is clearer on the Flags field being included. This change breaks interoperability with the old implementation if EAP-TNC fragmentation is used. The old version would not accept the acknowledgement message with the added Flags octet while the new version accepts messagss with with both options.
