 * SECTION:nm-setting-dcb
 * @short_description: Connection properties for Data Center Bridging
 *
 * The #NMSettingDcb object is a #NMSetting subclass that describes properties
 * for enabling and using Data Center Bridging (DCB) on Ethernet networks.
 * DCB is a set of protocols (including 802.1Qbb, 802.1Qaz, 802.1Qau, and
 * 802.1AB) to eliminate packet loss in Ethernet networks and support the use
 * of storage technologies like Fibre Channel over Ethernet (FCoE) and iSCSI.
