FT_ETHER field; the ISIS spec doesn't say it's necessarily a 6-byte Ethernet address (and, if it's FT_BYTES, you can test it in a filter much the same way you test an Ethernet address). Make "isis_hello.lan_id" an FT_BYTES field rather than an FT_STRING field - it's an array of bytes, not a character string. Don't require that "system ID" fields be 6 octets; use the size value from the ISIS PDU header. (This means that PDUs containing "system ID" fields can't be described as C structures; dissect them by stepping the offset instead.) svn path=/trunk/; revision=2080
