Previously on the WG, we went thru a discussion on this, and the
consensus was that all interfaces (irrespective of ipv4 only, ipv6 only,
or ipv4 and ipv6) MUST join the broadcast-GID and obtain parameters for
all IPv4 and IPv6 groups from this one single broadcast-GID. We further
discussed changing the signature part of the address of the broadcast
group to reflect that it was IPv4 and IPv6 agnostic, but maintained the
IPv4 signature to make it easier for current implementations to make any
required changes to adapt to this rule.
