network device. This is used by the bootwrapper to interpret
MAC addresses passed by the firmware when no information other
than indices is available to associate an address with a device.

+ i.e., "mii" (default), "rmii", "gmii", "rgmii", "rgmii-id", "sgmii",
+ "tbi", or "rtbi". This property is only really needed if the connection
