各个版本的手册：
API 手册
- API 手册
介绍了当前版本的DPDK的 模块，源码（example例子的源码，各个文件分布，头文件、函数的源码等）；
guides 手册
如上所示， 比较重要的几个方面是：
Getting Started Guide for Linux
参见：dpdk 21.11 Getting Started Guide for Linux 主要分为：
- 依赖
系统参数、驱动 - 编译
如何编译 dpdk - 启动参数
eal 启动参数解释 - 其他功能点
比如： rte_kni, 孤立 cpu, 性能调优点
Programmer’s Guide
详细介绍 DPDK 中的各个功能模块、lib库等。
比如： eal参数、各个组件/lib库（比如：rcu、ring、eal库，mempool, mbuf, rte_flow等等）/工具的原理、使用；
HowTo Guides
功能：
展示多个特性是如何测试的「包含：client怎么发包，测试程序怎么配置，怎么查看功能生效」以及 提供的一些 debug调试、故障排除/抓包/问题定位的建议。
参见：HowTo Guides
比如：测试 rte_flow
testpmd 配置 rte_flow;
client: 使用 scapy 发送包；
testpmd: 查看输出
DPDK Tools User Guides
dpdk 工具：比如
- dpdk-devbind
网卡和驱动的绑定、解绑定、查看；
参见：dpdk-devbind Application - dpdk-pmdinfo Application
展示 一个 pmd（dpdk程序）的硬件支持情况。
参见：dpdk-pmdinfo Application
范例： #./dpdk-pmdinfo -t /opt/xxx/bin/dpvs 简单举支持的几个网卡驱动，如下所示：
# 查看两个接口(port_0,port_1)的接口统计；
# ./dpdk-proc-info -- -p 3 --xstats
EAL: No legacy callbacks, legacy socket not created

功能：作为备程序，抓取dpdk主程序进入，出去的流量，写入到文件中。
前提条件：dpdk主程序中存在初始化包抓包框架，已知testpmd初始了该框架，其他的dpdk程序没有初始化。
区分：和dpdk-pdump 程序区分。
参见：DPDK packet capture libraries and tools
Testpmd Application User Guide
testpmd 是dpdk中很重要的一个example app, 可以测试多种场景。
