You could try the attached patch. It adds carpdev support. You'll have
to recompile ifconfig to make use of it.
This patch has some shortcomings that I wanted to address for a long time
now, but never found the time to do so. Mostly that IPv6 over CARP is
broken with this patch. Everything else is supposed to work and I'd like
to hear if you experience otherwise (success stories welcome, too). This
is from back in early January, but should apply to RELENG_7 and HEAD w/o
too much trouble.
Any feedback appreciated!
