Yes, I agree that a set function that doesn't always set is not
entirely nice, but the part I wanted to get reviewed and hopefully
accepted is PATCH 2/5. If that gets accepted, then I'm all open to
suggestions to improve this PATCH 3/5 by either renaming the function
to a more appropriate name, or change its behavior, depending on
reviewers suggestions.

Maybe of_set_mac_address() should simply be setting it, and callers are
responsible for checking with of_get_mac_address() first if no MAC
address is already set?

Best regards,

Thomas
