Some drivers/NICs don't support changing the MAC address at all, or
only badly. Seems you can change it, but maybe after changing it, the
NIC takes a very long time to get carrier (cable-plugged in) back. If
that's the case, maybe configure "carrier-wait-timeout". Read `man

In any case, check the level=TRACE log.
