The Devicetree Specification, Release v0.3 specifies in section 4.3.1 a "Network Class Binding". This covers MAC address and maximal frame size properties. "local-mac-address" and "mac-address" with a fixed "address-size" of 48 bits are already in the ethernet-controller.yaml schema so move those over. Keep "address-size" fixed to 48 bits as it's unclear if network protocols using 64-bit mac addresses like ZigBee, 6LoWPAN and others are relevant for this binding. This allows mac address array size validation for ethernet and wireless lan devices. "max-frame-size" in the Devicetree Specification is written to cover the whole layer 2 ethernet frame but actual use for this property is the payload size. Keep the description from ethernet-controller.yaml which specifies the property as MTU.
