Greetings,

I have extended the EIGRP packet dissector at epan/dissectors/packet-eigrp.c
with the ability to recognize two new flags in the EIGRP header - the Restart
flag and the End-Of-Table flag. These flags were originally introduced a couple
of years ago as a part of the Non Stop Forwarding support for EIGRP but they
are being used also during normal EIGRP operation to allow for graceful
restart. More information can be found here:

http://www.cisco.com/en/US/technologies/tk648/tk365/technologies_white_paper0900aecd8023df74.html

I am attaching the patch file and an EIGRP capture file to demonstrate the
presence and use of the new flags. I would like to ask you to kindly review the
changes and if considered acceptable, add them to the EIGRP packet dissector.

Best regards,
Peter
