Subject: [PATCH net-next 0/2] Enable 2.5Gbps speed for stmmac

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.
