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.)

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

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

Regards,
Asaf Penso

Subject: RE: dpdk rte rss flow with sriov


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?

Subject: dpdk rte rss flow with sriov



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
