VPP vnet/flow infrastructure简介 VPP提供了vnet/flow infrastructure来利用硬件网卡的卸载能力。当使用DPDK plugin作为基础IO插件时, dpdk plugin使用rte_flow来支持这些flow类型。 vnet/flow支持的flow类型有: Ethernet_type, IPv4, IPv6, IP4_N_TUPLE, IP6_N_TUPLE, IP4_L2TPV3OIP, IP4_IPSEC_ESP, IP4_IPSEC...

物理网卡上的DMA将数据包写入到内存中的rte_rx_queue; 应用程序通过PMD的形式轮询从rte_rx_queue读取数据包。 参数解析 1、imissed 参数 在dpdk处理rx 方向队列的处理函数逻辑如下所示: voideth_rx_queue_stats_get(void *vqueue, struct rte_eth_stats *stats) { 此处略去处理逻辑; stats->imissed += i...

I would like to configure RTE flow and redirect certain packets to queue 0. When this is done, I don't want other packets to use queue 0 due to RSS. Is there a way to disable RSS on set of rx-queues? -Nikhil -=-=-=-=-=-=-=-=-=-=-=- ...
