Hi

Is this possible to use dpdk rte rss flow with a vf sriov, or is it an option available only for real interface?
I use dpdk 19.11 and a Mellanox card 100G with mlx5

Perhaps I didn’t ask correctly

My vm have a vf sriov,

The dpdk application will create x rx queues on the vf as it should have done for a pf

I expect traffic to be spreaded between the rx queues according to rte_flow rss defined (RTE_FLOW_ACTION_TYPE_QUEUE or RTE_FLOW_ACTION_TYPE_RSS)
Asaf: I am not asking about the RTE_FLOW_ACTION_TYPE_VF – When you said Mellanox support where you referring to RTE_FLOW_ACTION_TYPE_VF?

I understand your scenario.
I want referring to action VF.

Can you share the testpmd commands line you use in the VM?

My question was theorical, is it possible to do the same load balance with the rss flow for vf as for pf for inner ip over gre, but then I tried and failed to initiate the testpmd application  and also my own application.

I sent a separate email about it, but still didn’t succeed to find the problem – with mail title “sriov net_mlx5 error - Unexpected error in DR drop action support detection”
That was the content of the mail -


  1.  Dpdk version: 19.11 (dpdk-stable-19.11.11)
  2.  Version of rdma core is 26.0 (from config.h #define PACKAGE_VERSION "26.0")
  3.  “Unexpected error in DR drop action support detection”  message is coming from rte_eal_init
  4.  “DPDK: Error starting or stopping port  -12”  is coming from rte_eth_dev_start

Here is the code of the program I run ( I run it with one rx queue and one tx queue), same program run for real interface (pf not vf)
I run it on vm (over esxi – vmware ) I don’t have access to host
https://coliru.stacked-crooked.com/a/6e2b9cd6cf047048
Here is the output of the program I run
/home/deployment/testReceiver  --log-level='.*',8 -l 7,0-15   -w 0b:00.0

Testpmd also failed to initiate with same parmeters

(I succeeded to run on another host with pf with dpdk19, and also +/- same code with dpdk17 with vf and pf.)
