The idea is to specify kni interface with an ip address, and isolate all traffic target at the address to a dedicated nic rx-queue, which may eliminate disturbances of dataplane when overload. Note that not all nic can support this flow type under the premise of sapool, and an additional rx queue is required, which is configured into dpvs's kni worker.

@ywc689 您好 我测试使用最新devel分支包含 kni rx队列独立的这个merge ，通过dpip flow命令使管理口ip，OSPF流量走kni队列，经过实际压力测试发现在业务核流量达到瓶颈时候（压测单个lcore开始丢包，或多个lcore到达瓶颈都会影响）依然会影响到独立kni队列的管理口ip ，和OSPF流量导致时延、丢包（测试过程中通过dpdk-pdump抓包确认管理口ip,ospf只走kni队列）。我看merge给出的测试用例是通过在业务lcore上delay 1ms模拟得出验证结果kni rx独立后业务流量过载的情况下不影响kni流量，我也测试模拟过，模拟结果也一样不影响，但是目前在实际流量压力测试下还是会影响。这块目前有点怀疑是否是网卡rss相关底层影响（我测试使用的网卡是82599ES 10-Gigabit）？目前还没什么思路，所以请教一下，或者这块是否有经过实际流量压测的验证结果。 |
