1.首先移除老网卡驱动

#ifconfig eth0 down

#rmmod tg3

#cd /lib/modules/$kernel version/kernel/drivers/net

#mv tg3.ko tg3.ko.backup

2.重新安装网卡驱动

2.1.下载并解压驱动包

#cd /usr/local/src

#tar xvzf tg3-version.tgz

2.2. Build the driver tg3.o as a loadable module for the running kernel.

CD tg3-version

make clean

若make clean 报错说No kernel source directory provided,则应安装kernel-devel

#rpm –ivh kernel-devel-version.rpm

make; make install

2.3. 卸载加载驱动模块并测试.

rmmod tg3

modprobe tg3

No message should be returned if this command runs properly.

2.4. 给网卡配置Ip地址并检测联通性

3.重新查看网卡驱动信息用以下命令

#ethtool  -i eth0
