/*
* LMP as a standard has shown a remarkable ability to get completely rewritten
* across minor versions of the draft. This file currently implements
* three versions of LMP; IP based versions described in draft-ietf-ccamp-lmp-02.txt and
* draft-ietf-ccamp-lmp-03.txt, and the new UDP based version in draft-ietf-ccamp-lmp-09.txt.
* The -09 version is the default; the version being dissected can be changed from
* the LMP protocol preferences
