Well clearly at least this one does not have any valid hardware
mac address, the hardware mac address is broken with all zeroes.

It seems that you can easily add a check for empty mac address, no?
And you already showed a version that falls back to a random mac

The fact that is old does not change a thing, we still need to
support it no matter what the data sheet and your system design
says. A fix that breaks other things is not really a fix :)

Sounds like there are multiple variants of the wl12xx
available then.
