Subject: [PATCH net-next v2 0/2] Enable 2.5Gbps speed for stmmac
Date: Mon,  5 Apr 2021 19:29:51 +0800	[thread overview]
Message-ID: <20210405112953.26008-1-michael.wei.hong.sit@intel.com> (raw)

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.
