Well, the only MUST attributes we seem to be missing are HopLimit and MTU
(P_Key, Q_Key and SL are all copied from the broadcast group when
creating a new multicast group).

I guess we should definitely do HopLimit and MTU, since those are
MUSTs.  The only other attribute we look at is Rate, so I guess we
should set that also.
