接续前节. 7 PMD (Poll Mode Driver) A Poll Mode Driver (PMD) consists of APIs, provided through the BSD driver running in user space, to configure the devices and their respective queues. In addition, a PMD accesses the RX and TX descriptors directly with…

ref: Dpdk programmer’s guide 1.  概述 dpdk不仅提供针对物理和虚拟网卡的pmd驱动(Poll Mode Drivers),还提供两个纯软件的pmd驱动,libpcap pmd就是其中之一.Libpcap pmd使用libpcap库读写报文,读写的源可以是文件,也可以是使用Linux内核驱动的物理网卡. 在没有或不方便配置物理网卡的机器上,使用libpcap pmd可以帮助dpdk应用开发人员进行功能性测试或代码调试:更重要的是,EAL(Environment…

代码部分 整个L3fwd有三千多行代码,但总体思想就是在L2fwd的基础上,增加网络层的根据 IP 地址进行路由查找的内容. main.c 文件 int main(int argc, char **argv) { /*......*/ /* init EAL */ ret = rte_eal_init(argc, argv); if (ret < 0) rte_exit(EXIT_FAILURE, "Invalid EAL parameters\n"); /*......*/ /…
