linux查找网卡模块及驱动信息

Linux内核模块文件命名方式一般＜模块名称.ko＞格式，Centos7系统内核模块集中存
在/lib/modules/`uname -r`/目录下。模块名称都在modules.*文件中。

#查看设备是否已经识别网卡：

[root@rc ~]# lspci | grep -i eth
02:01.0 Ethernet controller: Intel Corporation 82545EM Gigabit Ethernet Controller (Copper) (rev 01)
02:05.0 Ethernet controller: Intel Corporation 82545EM Gigabit Ethernet Controller (Copper) (rev 01)
02:06.0 Ethernet controller: Intel Corporation 82545EM Gigabit Ethernet Controller (Copper) (rev 01)

#查看网卡的驱动和模块：

[root@rc ~]# lspci -vv -s 02:01.0 | tail -n 3
        Kernel driver in use: e1000
        Kernel modules: e1000

[root@rc ~]# lspci -vv -s 02:05.0 | tail -n 3
        Kernel driver in use: e1000
        Kernel modules: e1000

[root@rc ~]# lspci -vv -s 02:06.0 | tail -n 3
        Kernel driver in use: e1000
        Kernel modules: e1000

#查找网卡的模块和查看模块信息：

[root@rc ~]# lsmod | grep e1000
e1000                 137624  0 

[root@rc ~]# modinfo e1000
