I don't understand how all of this works and why ipv6_add_addr(), which
seems designed explicitly to exclude multicast addresses, should accept
them and what all of the possible fallout might be from such a change.
Your commit message is way too terse and makes it impossible to evaluate
your change. Really, a change of this nature should have a couple paragraphs
of text explaining the existing situation, what is wrong with it, how you
are fixing it, and why you are fixing it that way.
Thanks.
