Thanks for doing this.

Longer term we really need an abstract interface by which
architectures can provide a "system" or "firmware" MAC address
which applies to a given 'dev'.

Because these SPARC ifdef'y things really should propagate to
driver after driver after driver.

I'll see if I can cook something up.
