back to the proper order when this property is set to 2
when it obtains the mac address from efuse.
-- local-mac-address: the driver is designed to use the of_get_mac_address api
- only if efuse-mac is 0. When efuse-mac is 0, the MAC
- address is obtained from local-mac-address. If this
- attribute is not present, then the driver will use a
- random MAC address.
- "netcp-device label": phandle to the device specification for each of NetCP
sub-module attached to this interface.
+The MAC address will be determined using the optional properties defined in
+ethernet.txt, as provided by the of_get_mac_address API and only if efuse-mac
+is set to 0. If any of the optional MAC address properties are not present,
+then the driver will use random MAC address.
