The purpose of the packets library is not carved in stone, but I've
been regarding it mainly as a grab bag for stuff that doesn't have a
clear place elsewhere in the tree. "benign" packets fall into that
category I think, but for LACP and CCM it seems less clear--we have
LACP and CFM files. Anything that is esoteric and protocol specific
would seem well suited to go into protocol-specific .c and .h files
when we already have them. Not sure why we'd banish it to some
