Odd that the marvel sky2 allows just that, but supplies no documentation.

I can supply some kind of usage description/example, showing how to use this feature to pull in the MAC address from u-boot and route it to the i210. Just uncertain as how to name the respective file. igb.txt or i210.txt come to mind. Do you prefer one over the other?
