[root@localhost zhou]#

4、显示网口驱动信息  ethtool -i dev

[root@localhost zhou]# ethtool -i ens33 
driver: e1000

firmware-version: 
expansion-rom-version: 
bus-info: 0000:02:01.0
supports-statistics: yes
supports-test: yes
supports-eeprom-access: yes
supports-register-dump: yes
supports-priv-flags: no
[root@localhost zhou]#
