This patchset enables 2.5Gbps speed mode for stmmac. Link speed mode is detected and configured at serdes power up sequence. For 2.5G, we do not use SGMII in-band AN, we check the link speed mode in the serdes and disable the in-band AN accordingly.
iperf3 and ping for 2.5Gbps and regression test on 10M/100M/1000Mbps is done to prevent regresson issues. 10Mbps host@EHL$ ethtool -s enp0s30f4 duplex full speed 10 [ 310.132264] intel-eth-pci 0000:00:1e.4 enp0s30f4: Link is Down [ 312.438102] intel-eth-pci 0000:00:1e.4 enp0s30f4: Link is Up -
