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. Hotplug VF

  4. 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. Add flow rule action "count" for counter query

  12. Validate and create the flow rule

  13. Check the traffic from VF to TST

  14. Check the traffic at least reached PF or representor

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

Parameters:

flow_rule_pattern

Flow Rule pattern

count

Count offloaded packets if TRUE

use_dpdk_driver

Use DPDK driver on VF if TRUE, use kernel driver otherwise

nb_pkts

Number of offloaded packets to send

iut_client

TRUE - IUT is client, FALSE - IUT is server
