I understand this is not good, but currently this is simple solution to
handle base MAC configuration for different boards which has this PP,
otherwise it needs to by supported by platform drivers. Is there some
generic way to handle this ?

If the HW is not capable holding the mac, I think that you can have it
in platform data. The usual way for such HW is to generate random mac.
module parameter is definitelly a no-go.

And i already suggested it should be a device tree property.
