[Phishing Risk] [External] Re: Changing ethernet port speed

[Zhang Jian]

Hi Bruce;

Where are you want to set the duplex and speed?

For linux, I use ethtool. See:
https://phoenixnap.com/kb/ethtool-command-change-speed-duplex-ethernet-card-linux
For u-boot, I think you need use `mdio` to change the register of
`phy`.(I'm not sure if any better way.).
