Hi Vivien
Terminology question. This function is used to add a multicast MAC
address to the switch tables. I've always considered a multicast group
as an IP layer thing. But this documentation is also considering a
multicast group to be a layer 2 thing.
Does the bridge code use multicast group when referring to L2?
Thanks
