For example, 100Gbps can be achieved using two lanes of 50Gbps or four lanes of 25Gbps. When use different lanes, the port cannot be up. This patch add support setting lanes and report lanes. In addition, add a device capability RTE_ETH_DEV_CAPA_SETTING_LANES When the device does not support it, if a speed supports different numbers of lanes, the application does not knowe which the lane number are used by the device.
