序

前一步做了pf_ring的编译，在pf_ring.ko没安装之前，pf_ring自带的例子大部分是不生效的。
如果在开发机，在pf_ring编译完后，运行make install 可以安装pf_ring.ko.
但是考虑到部署时，是没有开发环境的，需要写一个脚本，将驱动部署好。
花了一上午时间弄了一个脚本，还挺好使的。

脚本下载点

pf_ring_case_v1.1.zip
* 加入了安装pf_ring.ko的脚本
* 修正了一个测试工程的Makefile,加入了共用头文件的包含路径

安装脚本 install_pf_ring_driver.sh

#!/bin/bash
# @file install_pf_ring_driver.sh
