Hmm. carppeer does not seem to like an inet6 address to work around
that. I wonder what happens if you dual-stack a carp interface with a
carppeer - I remember having some mysterious issues after which I've
been running a separate carp if for ipv6. OTOH I have dual-stacked
carppeer-less carp if's that show no problems. Perhaps I can find time
to investigate.
