This patchset enables 2.5Gbps speed mode for stmmac and xPCS. 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 speed 10 duplex full autoneg on [ 76.022186] intel-eth-pci 0000:00:1e.4 enp0s30f4: Link is Down [ 79.420699] intel-eth-pci 0000:00:1e.4 enp0s30f4: Link is Up -
