You have to watch out, though. Most interfaces I know of only support a
limited set of multicast addresses (DEQNAs, I think, just have a table
for fourteen or so addresses in general). You don't really want to end
up having to listen to each and every packet in a multiprotocol gateway,
just because your multicast address table in the EThernet device overflows.
