The attached tentative patch makes IPv6 autoconf depend on the
availability of IFF_MULTICAST. This is admittedly a bit of a hack, but
it makes sense, since DAD and router solicitation do rely on multicast.

I disagree.  The node MUST NOT assign live address on
that interface.

I'm not sure I understand. The Xen bridge devices get fe:ff:ff:ff:ff:ff
as MAC address.  Which is a bit hackish, but that seems to be the way
the Xen folks want to do it.

They should be using random_ether_addr() or putting some per instance
specific info into the address.
