It might make sense to look at adding a module parameter to control
this behavior similar to what was done for ixgbe for
"allow_unsupported_sfp".
Otherwise such a failure is likely to end up causing other issues and
be harder to debug if it is just being automatically worked around as
the user may not see the issue as it is only being reported as
Basically you could check for it here and either run the old code, or
allow the new code that would assign a random MAC address.

We would probably want to make this a dev_err instead of just a
dev_info since the MAC address failing is pretty signficant. Also the
message may be better as "Invalid MAC address. Assigned random MAC
address". That way if somebody were to be parsing for the message they
would still find it since "MAC" hasn't been changed.

Dear Lixue,
Thank you for the patch. Please tag patch iterations with a version.
(Use `-v 2` in `git send-email` for example.)

Maybe remove this sentence, or rephrase.

Please reflow for 75 characters per line. (More words fit in one line.)

Is there a valid MAC address that should be only used for testing. Maybe
that can be used. Maybe also log the address.
Lastly, please fully capitalize MAC.
