Given that IPv6 relies upon multicast working, and multicast snooping
is a kernel configuration option, and MLD messages will only be sent
when whenever the configuration on the target changes, and there may
not be a multicast querier in the system, who does that ensure that
IPv6 can work on a bridge where the kernel configured and built with
multicast snooping enabled?
