I know this, and it is not a documentation of the protocol, it only
explains how to use the carp pseudo-device.

Where have you found this paragraph? It sounds strange, because it
contradicts the carp(4) manpage which don't state at all that CARP can
syncronize state table entries. According to the manpages, it rather seems
that CARP and pfsync are independent protocols, with different protocol
