i was able to apply those patches to 5.1-RELEASE without too
much trouble but there is a more complete and current
implementation in kame.  just the igmpv3 portion of kame was
split out as a separate patch for netbsd available here:
  http://www-sop.inria.fr/planete/Hitoshi.Asaeda/igmpv3/

as of last fall, kame was waiting for the igmpv3 sockets api to
be published as an rfc (it was an internet-draft at the time) to
merge igmpv3 into the core bsd distributions.
(see http://www.kame.net/roadmap-2003.html).

in january, the api draft was published as rfc 3678.  what is
the process by which code is merged from kame to freebsd?  is
it just a matter of somebody extracting the appropriate patches
and submitting them?
