From: Rafał Miłecki <rafal@milecki.pl>
U-Boot's "ethaddr" environment variable is very often used to store *base* MAC address. It's used as a base for calculating addresses for multiple interfaces. It's done by adding proper values. Actual offsets are picked by manufacturers and vary across devices.
