Simulate HW offload
===================

.. toctree::
	:hidden:

	group_representors-ovs_decap_hw_offload-run.rst

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

#. Negotiate the NIC's ability to deliver tunnel IDs to the PMD

#. Bind DPDK driver on a VF

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

#. Hotplug the representor of the VF

#. Hotplug VF

#. Make flow rule pattern and template

#. Start PF, VF and representor ports

#. Since DST addresses are alien, enable promiscuous mode on IUT

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

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

#. Make flow rule action VF (when receiving on IUT) or PHY (when receiving on TST)

#. Validate and create the flow rules

#. Check the traffic from VF to TST

#. Check the traffic at least reached PF or representor

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