- unify the IS-IS CLV space IS-IS uses a unified CLV space across all Level and PDU Types there is no need to define PDU- and Level- Specific CLV Types; - clean up Authentication CLV TLV #10 is the official supported TLV for carrying authentication information- todays code displays TLV #10 as non-standard which is wrong; also the notion of "Domain" "Authentication" and "Link" password has disappeared from contemporary routing SW; - add IP Authentication CLV dissector this CLV is depreciated - however it is using different semantics than TLV #10 so we need a dedicated dissector; - add Checksum CLV dissector add support for RFC 3358 Checksum CLVs majority of code re-used from the LSP checksum verification dissector. svn path=/trunk/; revision=9204
