And a device ID is bound to only one or two rates. So some cases hns3 driver only reports the FEC capabilities corresponding to the rate. But hns3 supports speed switching function, which causes the FEC capabilities of other rates are not reported. So this patch reports the FEC capabilities by the speed capabilities of the network port.
