找到指定网卡

其中eth0是有线网卡，

wlan0是无线网卡，

lo是localhost

查询指定网卡信息

ethtool -i [网卡名]

输出：
driver: r8168
version: 8.048.00-NAPI
firmware-version: 
expansion-rom-version: 
bus-info: 0000:01:00.0
supports-statistics: yes
supports-test: no
supports-eeprom-access: no
supports-register-dump: yes
supports-priv-flags: no

例如：ethtool-i enp1s0；需要注意driver，相当于驱动编号。
