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 Andrew
