IBTA GUIDs are EUI-64. The only issue I recall was whether the polarity
of the U/G bit was consistent with IEEE. This was updated at IBA 1.2. It
now says "manufacturer assigns EUI-64 with global scope set. May also
assign additional EUI-64 with local scope."

This is needed. IPv6 multicast mapping is slightly different from the
IPv4 mapping.
