     * Beside explicitly specifying a MAC address, the special values "preserve", "permanent",

     * "preserve" means not to touch the MAC address on activation.
     * "permanent" means to use the permanent hardware address of the device.
     * "random" creates a random MAC address on each connect.
     * "stable" creates a hashed MAC address based on connection.stable-id and a
     * machine dependent key.
     * "stable-ssid" creates a hashed MAC address based on the SSID, the same as setting the
     * stable-id to "${NETWORK_SSID}".
     *
     * If unspecified, the value can be overwritten via global defaults, see manual
     * of NetworkManager.conf. If still unspecified, it defaults to "preserve"

     *
     * On D-Bus, this field is expressed as "assigned-mac-address" or the deprecated
