我有一块光纤 X710 NIC,运行速度为 10,000Mb/s(SFP+)。我用它ethtool
来展示它的功能:
ethtool enp1s0f0
Settings for enp1s0f0:

1000baseX/Full

Supported FEC modes: Not reported

如您所见,支持 1GE。但是,当我尝试更改其速度时,出现此错误:
sudo ethtool -s enp1s0f0 speed 1000
Cannot set new settings: Operation not supported
not setting speed
您对这个问题有什么想法吗?我该如何更改速度模式?
