I also found this one helpful

The CFxxxx Series

RFC 2153 describes a method of usings a "pseudo OUI" for certain
purposes when there is no appropriate regular OUI assigned.  These are
listed here.

CF0001  Data Comm for Business                                  [McCain]

I remember we had IBM Token-Ring equipment and they suggested
to always use "CF..." and never rely on the programmed MAC for SNA.

Kind regards
Peter

You can probably find examples online, but in a nutshell this
does exist.

Set bit b2 to 1, "locally assigned".
Default is 0, "globally unique" (OUI assigned).

Cheers,
