Dfly's carp lacks arp based load balance (at least I think so) and it
does not support inet6 (use it w/ inet6 at your own risk, at least I
don't think inet6 carp works on dfly).  We lack unicast-peer
configuration support; we still use the multicast based protocol.  The
good side is inet4 fail-over works as expected and it supports TSO and
TXCSUM if the backend interface supports TSO and TXCSUM.
