I agree that both of your recommendations might make the code better,
but I don't see why we would need to revert it.  The code does the
intended function for many use cases, even if you've identified a few
where calling `dev_set_mac_address` would be better.

Either you or I can send a "Fixes: " on this commit to improve the
handling as you're proposing.  While the change is likely trivial, I
have not had any chance to test it yet, so I've not sent it up myself.
If you want to refactor the code to reduce duplication, I think that should
be an entirely separate proposal.
