Some speeds can be achieved with different number of lanes. 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 set add support setting lanes for ethdev In addition, modify the testpmd and hns3 driver to adapt to it.
