Please clarify if this is a drivers/net/ethernet policy or 
that is true for the larger subsystem. There are a few
networking drivers that have a mac_addr module parameter. I
personally used drivers/net/ethernet/8390/pcnet_cs.c as inspiration
for my patch.

Understood. Stephen Hemminger has provided a patch that I can try
and I will report back with the results.
