vpp: Initial support of VPP vSwitch
Support of VPP was implemented into VSPERF. Initial implementation uses step driven testcases to configure P2P, PVP and PVVP network scenarios. These testcases were prepared for three RFC2544 traffic types, i.e. throughput, continuous stream and back to back. VPP configuration is driven by new configuration option VSWITCH_VPP_ARGS. It is possible to use three types of l2 port connection supported by VPP, i.e. l2 xconnect (default), l2patch and l2 bridge features. Configuration is driven by parameter VSWITCH_VPP_L2_CONNECT_MODE.

+Executing VPP tests
+^^^^^^^^^^^^^^^^^^^
+
+Currently it is not possible to use standard scenario deployments for execution of
+tests with VPP. It means, that deployments ``p2p``, ``pvp``, ``pvvp`` and in general any
+:ref:`pxp-deployment` won't work with VPP. However it is possible to use VPP in
+:ref:`step-driven-tests`. A basic set of VPP testcases covering ``phy2phy``, ``pvp``
+and ``pvvp`` tests are already prepared.
+
+List of performance tests with VPP support follows:
+
+* phy2phy_tput_vpp: VPP: LTD.Throughput.RFC2544.PacketLossRatio
+* phy2phy_cont_vpp: VPP: Phy2Phy Continuous Stream
+* phy2phy_back2back_vpp: VPP: LTD.Throughput.RFC2544.BackToBackFrames
+* pvp_tput_vpp: VPP: LTD.Throughput.RFC2544.PacketLossRatio
+* pvp_cont_vpp: VPP: PVP Continuous Stream
+* pvp_back2back_vpp: VPP: LTD.Throughput.RFC2544.BackToBackFrames
+* pvvp_tput_vpp: VPP: LTD.Throughput.RFC2544.PacketLossRatio
+* pvvp_cont_vpp: VPP: PVP Continuous Stream
+* pvvp_back2back_vpp: VPP: LTD.Throughput.RFC2544.BackToBackFrames
+
+In order to execute testcases with VPP it is required to:
+
+* install VPP manually, see :ref:`vpp-installation`
+* configure ``WHITELIST_NICS``, with two physical NICs connected to the traffic generator
+* configure traffic generator, see :ref:`trafficgen-installation`
+
+After that it is possible to execute VPP testcases listed above.
+
+For example:

+ $ ./vsperf --conf-file=<path_to_custom_conf> phy2phy_tput_vpp
