rte_config file

Hi.

I'm trying to use rte_flow API to do some packet steering to different queues,
but to no avail.

Important note here is that i'm working with VF (SR-IOV) inside VM. VM is
Ubuntu 20.04.

DPDK used is 21.11.1 (statically compiled). Tests are done with testpmd
application.

I did test the same rule with following DPDK drivers:
ixgbevf - NOT WORKING (x520)
mlx5 - WORKING
iavf - NOT WORKING (xxv710, xl710, e810).

Cards used are:

xx:00.0 Ethernet controller: Intel Corporation 82599ES 10-Gigabit SFI/SFP+
Network Connection (rev 01)
        Subsystem: Intel Corporation Ethernet Server Adapter X520-2

xx:00.0 Ethernet controller: Intel Corporation Ethernet Controller XXV710 for
25GbE SFP28 (rev 02)
        Subsystem: Hewlett Packard Enterprise Ethernet 10/25/Gb 2-port 661SFP28
Adapter

xx:00.0 Ethernet controller: Intel Corporation Ethernet Controller XL710 for
40GbE QSFP+ (rev 02)
        Subsystem: Intel Corporation Ethernet Converged Network Adapter
XL710-Q2

xx:00.0 Ethernet controller: Intel Corporation Ethernet Controller E810-C for
QSFP (rev 02)
        Subsystem: Intel Corporation Ethernet Network Adapter E810-C-Q2

Cards behave the same in different servers, but i did try it on sandybridge,
skylake and cascadelake architecture.

Drivers used (and versions):

ixgbe-5.12.5
ixgbevf-4.12.4
i40e-2.18.9
ice-1.7.16
iavf-4.2.7

Drivers versions are the same in host and guest (VM).

Main question here is - do those cards support rte_flow API applied over VF
port? If they do, what is wrong here? If needed i can provide more details.

Here is an example:

Warning! port-topology=paired and odd forward ports number, the last port will
pair with itself.
