Message

Sit, Michael Wei Hong March 25, 2021, 8:38 a.m. UTC 
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.
