 * The #NMSettingWimax object is a #NMSetting subclass that describes properties
 * necessary for connection to 802.16e Mobile WiMAX networks.
 *
 * NetworkManager no longer supports WiMAX; while this API remains available for
 * backward-compatibility reasons, it serves no real purpose, since WiMAX
 * connections cannot be activated.
