netlink error: link settings update failed netlink error: Invalid argument

[virasana]

Hi There,

I tried the command below, as per the README. But it does not work for me.

# ethtool -s enp3s0f2 speed 1000 autoneg off
netlink error: link settings update failed
netlink error: Invalid argument

I am using the following OS:

# cat /etc/os-release 
NAME="Linux Mint"
VERSION="21.3 (Virginia)"
ID=linuxmint
ID_LIKE="ubuntu debian"
PRETTY_NAME="Linux Mint 21.3"
VERSION_ID="21.3"

BUG_REPORT_URL="http://linuxmint-troubleshooting-guide.readthedocs.io/en/latest/"
PRIVACY_POLICY_URL="https://www.linuxmint.com/"
VERSION_CODENAME=virginia
UBUNTU_CODENAME=jammy

Any ideas?

Incidentally, the NIC is unable to negotiate 1000Mbps - it negotiates 100Mbps. I am on a GB router. Any ideas?

My ethtool shows the following:

# ethtool enp3s0f2
