Simulate HW offload

Make sure that offloading traffic to a virtual function works with RTE flow API

1. Hotplug the representor of the VF

2. Bind kernel or DPDK driver on a VF

3. If use_dpdk_driver :

   • Hotplug VF

4. If not use_dpdk_driver :

   • Add VF's kernel interface and bring it up

5. Create a big enough mempool for PF, VF and representor ports

6. Make flow rule pattern and template

7. Start PF, VF and representor ports

8. Check full traffic path (IUT - representor - TST) without flow rule

9. Make flow rule attributes with transfer and ingress or egress depending on traffic direction

10. Direct traffic to the VF (when receiving on IUT) or to the physical port (when receiving on TST)

11. If count :

    • Add flow rule action "count" for counter query

12. Validate and create the flow rule

13. For each iteration (i = 0; i < nb_pkts; i++):

    • Check the traffic from VF to TST

    • Only on the error path:

      • Check the traffic at least reached PF or representor

14. Destroy the flow rule and check the full traffic path again
