Subject: [dpdk-users] Is it possible to configure different default queues per port
Date: Fri, 21 May 2021 04:51:51 +0000	[thread overview]
Message-ID: <TU4PR8401MB047913D13ADD6F42A1ACC352EC299@TU4PR8401MB0479.NAMPRD84.PROD.OUTLOOK.COM> (raw)

Hi,

We are using DPDK 20.08 and Intel XXV710 NIC (firmware version 7.3)

We have a dpdk application running as 4 processes on 4 CPUs.

And, we have 4 ports for the ingress traffic.

* Each port has been configured with 4 Rx Queues (from 0 to 3) and each Rx Queue is bound to a unique CPU.

With RSS hashing mechanism, the incoming packets will get hashed and fall into one of the 4 queues.
But, when RSS hashing fails or cannot be done, the incoming packets are enqueued into Queue 0 on each port because this is the default queue.

Is it possible to change the default queue so that, for each port, there is a different default queue. Eg:
 - For port 0, the default queue is 0 ,
 - For port 1, the default queue is 1 and so on.



Regards,
Venkatesh
