Lwip friends,Is there a way for LWIP to register MAC addresses related to IPV4 or IPV6 multicast addresses to assist in multicast address filtering by the MAC (or possibly by upstream switches when supported - without using IGMP snooping - or whatever is used when MLD is used).
The NIC I use has the capability to filter Multicast Mac addresses (which can possibly reduce the load). I also have another NIC that is a virtualization NIC and can inform upstream switch(es) about the filtering.
Without this, a Multicast MAC destination is basically a broadcast ! (Of course, the filtering is probably done in LWIP at this point anyway).
(Or am I just on a wild goose chase ?) --Ivan
