Log message:
Automatically add a IPv6 link-local address to carp interfaces when the
virtual MAC address is set. Among other things, this makes route6d work
correctly on systems with carp interfaces.

In order to ensure backwards compatibility, we do not include IPv6
link-local addresses in generating the HMAC, but we accept HMACs with AND
without the link-local addresses. They will be added to the HMAC in a future
release.

In short: this change should only affect backwards compatibility for
IPv6 users who are manually adding link-local addresses on carp interfaces.
