This can be used to query if a received ethernet packet has an IPv6
multicast address, e.g. for IPv6 Neighbor Discovery Protocol.
Of course, ETHER_IS_MULTICAST is still preferred in the general case.

Hi, any thoughts on this?
This definition is used by NetApp as part of a larger set of changes that is not yet upstream-ready. It doesn't offer much value on its own, but helps reduce their local diff against FreeBSD.
I'd appreciate a prod in either direction of "looks good, go ahead" or "save it for the larger patch". Thanks.
For reference, this definition comes from RFC 2464, Section 7.
