SET failed on device eth0 ; No such device

这个问题就是你当前的驱动无法驱动RTL8111/RTL8168的网卡，你可在RTL官网上去找找看有没有linux 的相关驱动，若不行，那就只能尝试用r1000来驱动。我以前是8169的网卡就只能用r1000来驱动的。

在重启网卡的过程中出现如下错误：

shell# /etc/init.d/networking restart

* Reconfiguring network interfaces...

eth0: ERROR while getting interface flags: No such device

SIOCSIFADDR: No such device

eth0: ERROR while getting interface flags: No such device

SIOCSIFNETMASK: No such device

SIOCSIFBRDADDR: No such device

eth0: ERROR while getting interface flags: No such device

eth0: ERROR while getting interface flags: No such device

Failed to bring up eth0.

解决办法：

删除配置规则缓存文件，重启后会根据现在的网络配置重新生成，然后重启

shell# rm -rf etc/udev/rules.d/70-persistent-net.rules

shell# reboot

重启后会发现网卡正常启动
