Subject: [PATCH net-next v2 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.
Changes:
v1 -> v2
patch 1/2
-Remove MAC supported link speed masking
patch 2/2
-Add supported link speed masking in the PCS
iperf3 and ping for 2.5Gbps and regression test on 10M/100M/1000Mbps
is done to prevent regresson issues.
