RHEL/Linux下如何找出網卡驅動的內核模塊名稱
通過在dmesg裡(/var/log/dmesg)查找網卡名稱可得到網卡驅動的內核模塊名稱，適用於rhel6&5：
[root@station122 ~]# lsb_release -a
LSB Version: :core-4.0-amd64:core-4.0-noarch:graphics-4.0-amd64:graphics-4.0-noarch:printing-4.0-
amd64:printing-4.0-noarch
Distributor ID: RedHatEnterpriseServer
Description: Red Hat Enterprise Linux Server release 6.0 (Santiago)
Release: 6.0
Codename: Santiago
[root@station122 ~]# dmesg | grep eth
e1000: eth0: e1000_probe: Intel(R) PRO/1000 Network Connection
e1000: eth1: e1000_probe: Intel(R) PRO/1000 Network Connection
e1000: eth2: e1000_probe: Intel(R) PRO/1000 Network Connection
e1000: eth0 NIC Link is Up 1000 Mbps Full Duplex, Flow Control: RX
eth0: no IPv6 routers present
e1000: eth0 NIC Link is Up 1000 Mbps Full Duplex, Flow Control: RX
eth0: no IPv6 routers present
e1000: eth0 NIC Link is Up 1000 Mbps Full Duplex, Flow Control: RX
eth0: no IPv6 routers present
e1000: eth1 NIC Link is Up 1000 Mbps Full Duplex, Flow Control: RX
eth1: no IPv6 routers present
e1000: eth0: e1000_probe: Intel(R) PRO/1000 Network Connection
e1000: eth1: e1000_probe: Intel(R) PRO/1000 Network Connection
e1000: eth0 NIC Link is Up 1000 Mbps Full Duplex, Flow Control: RX
e1000: eth2: e1000_probe: Intel(R) PRO/1000 Network Connection
eth0: no IPv6 routers present
[root@station122 ~]# cat /var/log/dmesg | grep eth
e1000: eth0: e1000_probe: Intel(R) PRO/1000 Network Connection
e1000: eth1: e1000_probe: Intel(R) PRO/1000 Network Connection
e1000: eth2: e1000_probe: Intel(R) PRO/1000 Network Connection
[root@station122 ~]#
除此之外，rhel5下還可通過查看modprobe.conf文件（rhel6已無此文件）來確定：
[root@server1 ~]# lsb_release -a
LSB Version: :core-4.0-amd64:core-4.0-ia32:core-4.0-noarch:graphics-4.0-amd64:graphics-4.0-
ia32:graphics-4.0-noarch:printing-4.0-amd64:printing-4.0-ia32:printing-4.0-noarch
