Looking at udld.flags in the attached sample UDLD file from SharkFest Europe
shows that values 0x01 and 0x03 are seen in the capture file, while the
dissector (packet-idld.c) uses bitmasks 0x80 and 0x40 for udld.flags.rt
(Recommended timeout) and udld.flags.rsy (ReSynch). RFC 5171 packet format
definition confirms these bits are at the other end of the octet.
