FWIW, I like this approach, and mapping to/from this GID to the MAC
without a ND operation nicely divorces the RMDAoE stuff from the IPv6
stack.

What about multicast though? Switches are going to have trouble with
group membership lists for non IP packets.. Even just sending a ICMPv6
packet (with an IPv6 ethertype) isn't guaranteed to fix it.
