 * ether-get-mac-address

 * Retrieve the MAC address for the Ethernet interface associated
 * with the device handle.
 *
 * While it is common for platform device trees to provide the MAC
 * address in a property, some platforms may use single system-wide
 * MAC address in addition to interface-specific addresses, and the
 * rules about which one to use on a given interface are encoded into
 * the device tree itself, hence this hook.
