Most of this email was about the datapath implications.  I'll leave
those for Jesse.

Have you considered the OpenFlow implications?  OpenFlow itself is
somewhat Ethernet centric.  Improving this has been in discussion, in
various ways, in the "extensibility" working group at ONF for a couple
of years now, e.g. in these tickets:

    https://rs.opennetworking.org/bugs/browse/EXT-56
    https://rs.opennetworking.org/bugs/browse/EXT-111
    https://rs.opennetworking.org/bugs/browse/EXT-112

(If you don't have an account, you'll need to get one to view those
tickets.  That should be easy for anyone at an ONF member company,
including Cisco.)

EXT-56 was resolved with OpenFlow 1.2.  EXT-111 and EXT-112 are still
unresolved, but they are also quite vague.
