Pktgen-DPDK介绍
Pktgen-DPDK是6wind基于intel dpdk开发的一个发包工具；用于测试dpdk的包转发能力；
可以在https://github.com/Pktgen/Pktgen-DPDK看到其详细信息；
我的测试环境为REHL6.2系统;
下载源码方式
git clone http://github.com/Pktgen/Pktgen-DPDK.git 安装编译源码；
下载源码后进入Pktgen-DPDK/dpdk目录，执行安装；
make install T=x86_64-wr-linuxapp-gcc如遇下面的变量名重复定义错误；
In file included from /home/linzh/repo/Pktgen-DPDK/dpdk/lib/libwr_mcos/rte_mcos.c:81:

vim /home/linzh/repo/Pktgen-DPDK/dpdk/lib/libwr_mcos/rte_mcos_debug.h
%s/mInfo_t/mInfo_t_bak/g
%s/mcos_master_t/mcos_master_t_bak/g
设置环境变量；
export RTE_SDK=`pwd`
export RTE_TARGET=x86_64-wr-linuxapp-gcc
执行脚本进行安装配置；
./tools/setup.sh[6] Insert IGB UIO module
[7] Insert KNI module
[8] Setup hugepage mappings for non-NUMA systems设置hugepage 信息，我输入了1024，也就是分配1024个2M的内存，等于2G的内存空间；
运行11，进行一下dpdk的测试；在11中如果一个core源码，如果输入 F 敲回车， 也就是用 0至3这几个core去测试；
[11] Run testpmd application in interactive mode ($RTE_TARGET/app/testpmd)Option: 11
Enter hex bitmask of cores to execute testpmd app on
Example: to execute app on cores 0 to 7, enter 0xff
bitmask:F
输入F敲回车后，
显示下面的部分信息，说明成功了
Interactive-mode selected

下面测试pktgen
进入Pktgen-DPDK/dpdk/wr-examples/pktgen目录；
执行make去编译pktgen;
运行setup脚本，去配置一下环境，这个脚本其实是配置了一下hugepage，和从新安装了一下intel网卡的驱动；
./setup运行doit去测试pktgen；
./doit如果发现报错；
EAL: coremask set to e
EAL: Auto-detected process type: PRIMARY
EAL: Detected lcore 1 as core 1 on socket 0
EAL: Detected lcore 2 as core 2 on socket 0
EAL: Detected lcore 3 as core 8 on socket 0
EAL: Setting up hugepage memory...

EAL: Virtual area found at 0x7f1a14e00000 (size = 0x80000000)

./doit: line 8: 3445 Aborted (core dumped) ./app/build/pktgen -c e -n 3 --proc-type auto --socket-mem 128,128 --file-prefix pg -- -p 0x14 -P -m "2.0, 3.1" -f test/set_seq.cmd
这应该是执行程序是，传入测参数报错；
--socket-mem 128,128./app/build/pktgen -c e -n 3 --proc-type auto --socket-mem 128 --file-prefix pg -- -p 0x14 -P -m "2.0, 3.1" -f test/set_seq.cmd-c 是指选择的core的掩码， e 等于 1110 也就是选择 1 、 2 、3 号core；
--proc-type 选择的auto ，如果是当前系统第一执行的dpdk相关的程序，选择primary模式，如果是第二是 secondary 模式；
--file-prefix pg 设置/mnt/huge/内存分配模块的文件名前缀；
-p 0x14 0x14 等于 00010100 , 选择你当前系统的其中2块intel相关网卡端口；
-P 使能网络混装模式，
-m "2.0, 3.1" 这是指一个矩阵模型，2.0 是指，在2号lcore上绑定的端口0 ， 3.1 是指在 lcore3 上绑定端口1
-f test/set_seq.cmd 最后导入pktgen的执行配置文件；在执行pktgen时，利用配置产生数据包；
