也是更新后出现的问题，一个月前的问题一直拖到现在，早发现早解决。

成功解决

分析原因，然后针对问题进行解决，第一种半吊子的方法不建议采用，还是得仔细思考。 网卡驱动出现了问题，找到与网卡对应的最新驱动进行安装。

1.PReparing the Driver Installation Package Before the sk98lin driver installation script can be invoked, the installation package needs to be unpacked:

2.Driver Installation

After the driver installation package is unpacked, execute the following commands to start the sk98lin driver build process: cd DriverInstall ./install.sh

Select the driver installation mode (see following sections).

NOTE: In case you have installed another driver module than the original Marvell driver you will be asked how to further proceed. You can ignore the fact, you can rename the other driver, or you can erase the driver. We recommend to erase the driver to avoid unwanted side effects and interdependencies.

Wait for the driver build process to finish.

Depending on the installation mode you selected, the driver is either compiled and installed, or a kernel patch is generated.

NOTE: Depending on your linux distribution, the name of your device may have changed after successful installation. In order to restore your old device, start the appropriate network configuration utility and rename the device.

3.Installation Mode

When selecting the installation mode, the driver sources shipped with the install package are compiled and the resulting driver module object file is installed to a suitable location (usually somewhere below directory /lib/modules/…).

No source files of the driver are installed into a kernel directory. Only the driver module object file and the man page of the driver are installed onto your system permanently.

Installation mode means that the build process runs automatically without any user interaction. In case of installation problems, the driver installation script autonomously tries to solve the problem (if possible).

After the compilation has finished, the initial system state and configuration is recovered and all (possibly) backed-up system files are restored from the initial configuration.

这篇写的不够简洁明了，主要是给自己的工作做个记录。
