以上因素叠加设备资源的分配方式,可能会导致rte_flow 的可用的类型的数量受到限制(比如:在有能力的硬件上也不支持 RSS 操作和RTE_FLOW共存;在博通Broadcom 网卡的 bnxt pmd 中之前就存在RSS和RTE_FLOW不可以同时开启的情况,后来还存在不允许设置rte_flow 的action 为 RxQueue_0)。 isolated mode的出现 DPDK的应用...
异步是指包转发的过程中,向硬件中变更,增减rte flow条目。它有个无锁队列。 准备好条目后,放入队列。然后push进硬件,再用api pull出flow的加载结果。 编程模型见下图: 五isolated mode 通常,流量先过flow规则,然后再 rss或者通过其他全局接口定义 进入不同的queue。 isolated模式使包的流量直接通过flow规则进行转发...
