That's great that we have official OUIs now, but I have to NACK this
patch as is.

The problem is a host with the old OUIs will not recognize a remote
unit with the new OUIs, and vice versa.

Even though the new ids could be added to the unit driver's id_table,
(which would let hosts with the new OUI connect to either OUI remote),
it wouldn't let 3.19- hosts connect to 3.20+ hosts.
