检查我的以太网控制器是否支持千兆以太网

Question

是否有我可以在 Ubuntu 中发出的命令来明确查看我的以太网控制器是否支持千兆以太网？

以 rootethtool eth0身份运行，如果 eth0 是有问题的 NIC。你会得到如下输出：

Settings for eth0:

Supported link modes:   10baseT/Half 10baseT/Full 
                        100baseT/Half 100baseT/Full 
                        1000baseT/Half 1000baseT/Full
