+Subject: of/net: Add MAC address to of tree
+
+The label-mac logic relies on the mac-address property of a netdev
+devices of-node. However, the mac address can also be stored as a
+different property or read from e.g. an mtd device.
+
+Create this node when reading a mac-address from OF if it does not
+already exist and copy the mac-address used for the device to this
+property. This way, the MAC address can be accessed using procfs.
