DPDK中的PMD全称是什么？本质是什么？（本质是Driver、是Polling的，异步的）
来源：好走旅游网
- PMD：Poll Mode Drivers，轮询模式驱动。注意是多个驱动
- 设计目的：异步通知和减少overhead
- Poll mode drivers (PMD) are designed to work without asynchronous notifications, reducing overhead
- 形式：提供so库进行处理，比如librte_pmd_vmxnet3.so、librte_pmd_memnic_copy.so
- 比如NVIDIA的kit介绍：Data Plane Development Kit (DPDK)：Achieve fast packet processing and low latency with NVIDIA Poll Mode Driver (PMD) in DPDK. DPDK是一个PMD，核心是一个driver
- NVIDIA Poll Mode Driver (PMD) is an open-source upstream driver embedded within dpdk.org releases 。
- NVIDIA的DPDK版本与mlx的关系：DPDK 2.0 release (mlx4) and DPDK 2.2 release (mlx5).
