Okay, can't argue with it ^^

They will probably just be happy the crazy noise they have been seeing
from current Panda MACs changing every session will go away, it doesn't
seem to add anything it's an OUI namespace MAC. In the patch case the
"locally administered" mac will be "stable".
Anyway since I understood it, I can see your idea is a cool approach,
it's up to TI what they will do about it but I guess it's OK with or
without it.
