This is what I have been advocating..
A quibble about multicast - AFAIK this is unsolved. I think some spec
needs to be agreed that documents what sort of multicast snooping
operations switches need to do, ie if IGMP joins imply that IBoE
traffic for the same DMAC is included in the join, or if IBoE requires
a seperate IGMP type process on its own ether-type. That would make it
much clearer what to do with MGIDs.
IPv4 could be handled by mapping a IPv4 multicast address within an
IPv6 mapped address, if necessary.
It would be nice to at least have a plan on how to integrate a
non-link local address, if that is ever necessary in future. An
extended AH with an additional 48 DMAC field seems reasonable to me?
