安装完dpdk、lua工具后，执行命令./pktgen -l 1-5 -n 6 -- -P -m "[2].0,[3].1,[4].2,[5].3"
报错如下：

要在pktgen根目录下执行就不会报错了：
cd /pot/pktgen-dpdk-pktgen-3.5.0
./app/x86_64-native-linuxapp-gcc/pktgen -l 0-4 -n 3 -- -P -m "[1:3].0, [2:4].1"
除了pktgen，还有其他压测工具。
推荐一个网络压测工具dperf项目https://github.com/baidu/dperf
，它实现了小型的TCP/UDP/http协议栈，实现了HTTP客户端/服务器，性能达到100Gbps，每秒1千万HTTP新建，几十亿并发连接数，里面有设计文档。它经过Linux基金会评审，成为了DPDK生态项目哦。dperf运行在用户态很方便修改、调试，对学习TCP协议栈很有帮助。谢谢。
