It is up to the board to decide whether to use this MAC address or not: - Odroid-C1 uses the MAC address from the eFuse - EC-100 seems to read the MAC address from eMMC Add the nvmem cell which describes the Ethernet MAC address. Don't assign it to the Ethernet controller, because depending on the board the actual MAC address may be read from somewhere else.
