Nope.  We definitely don't support it.  I don't know that we are
that close -- it still seems like a pain to have to allocate the
new host routes as we do the PMTU, clean 'em up when they expire,
etc.  It certainly would be nice to have, but then I've been saying
that for awhile, but I haven't written any code for it.  :-(
