[dpdk] SDK编译配置

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-16.07.2/x86_64-native-linuxapp-gcc/.config /root/src/thirdparty/dpdk/dpdk-stable-16.07.2/x86_64-native-linuxapp-gcc/.config.orig 
374,375c374,375
< CONFIG_RTE_LIBRTE_KNI=n
< CONFIG_RTE_KNI_KMOD=n
---
> CONFIG_RTE_LIBRTE_KNI=y
> 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。
