前言：
dpdk-16.07.2 与 内核Linux-3.10.0-514.6.1.el7.x86_64 编译的时候有个关于kni的错误

已知：
1. 学会了编译。
2. config已完成
配置：
修改文件 /root/src/thirdparty/dpdk/dpdk-stable-16.07.2/x86_64-native-linuxapp-gcc/.config 可以进行配置。
[root@dpdk x86_64-native-linuxapp-gcc]# diff /root/src/thirdparty/dpdk/dpdk-stable-16.07./x86_64-native-linuxapp-gcc/.config /root/src/thirdparty/dpdk/dpdk-stable-16.07./x86_64-native-linuxapp-gcc/.config.orig

> CONFIG_RTE_KNI_KMOD=y
[root@dpdk x86_64-native-linuxapp-gcc]#
这样就不编译kni了，就可以过了。
