regression: OVS/DPDK regression tests

A set of regression tests for verification of OVS/DPDK features was introduced. Following features are tested: * DPDK NIC Support * DPDK Hotplug Support * RX Checksum Support * Flow Control Support * Multiqueue Support * Vhost User * Virtual Devices Support * NUMA Support * Jumbo Frame Support * Rate Limiting * Quality of Service JIRA: VSPERF-539 Change-Id: I6c83e9c38e29f197a5236ac68c88d7045fef775b Signed-off-by: Martin Klozik <martinx.klozik@intel.com> Signed-off-by: Martin Goldammer <martinx.goldammer@intel.com> Signed-off-by: Richard Elias <richardx.elias@intel.com> Reviewed-by: Al Morton <acmorton@att.com> Reviewed-by: Christian Trautman <ctrautma@redhat.com> Reviewed-by: Sridhar Rao <sridhar.rao@spirent.com> Reviewed-by: Trevor Cooper <trevor.cooper@intel.com>

+OVS/DPDK Regression TestCases
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+These regression tests verify several DPDK features used internally by Open vSwitch. Tests
+can be used for verification of performance and correct functionality of upcoming DPDK
+and OVS releases and release candidates.
+
+These tests are part of integration testcases and they must be executed with
+``--integration`` CLI parameter.
+
+Example of execution of all OVS/DPDK regression tests:
+
+.. code-block:: bash
+
+   $ ./vsperf --integration --tests ovsdpdk_
+
+Testcases are defined in the file ``conf/integration/01b_dpdk_regression_tests.conf``. This file
+contains a set of configuration options with prefix ``OVSDPDK_``. These parameters can be used
+for customization of regression tests and they will override some of standard VSPERF configuration
+options. It is recommended to check OVSDPDK configuration parameters and modify them in accordance
+with VSPERF configuration.
+
+At least following parameters should be examined. Their values shall ensure, that DPDK and
+QEMU threads are pinned to cpu cores of the same NUMA slot, where tested NICs are connected.

+
+DPDK NIC Support
+++++++++++++++++
+
+A set of performance tests to verify support of DPDK accelerated network interface cards.
+Testcases use standard physical to physical network scenario with several vSwitch and
+traffic configurations, which includes one and two PMD threads, uni and bidirectional traffic
+and RFC2544 Continuous or RFC2544 Throughput with 0% packet loss traffic types.

+
+DPDK Hotplug Support
+++++++++++++++++++++
+
+A set of functional tests to verify DPDK hotplug support. Tests verify, that it is possible
+to use port, which was not bound to DPDK driver during vSwitch startup. There is also
+a test which verifies a possibility to detach port from DPDK driver. However support
+for manual detachment of a port from DPDK has been removed from recent OVS versions and
+thus this testcase is expected to fail.
+

+                                         ovs-vswitchd is launched.

+                                         after the hotplug. Note  Support of netdev-dpdk/detach has been
+                                         removed from OVS, so testcase will fail with recent OVS/DPDK
+                                         versions.

+
+RX Checksum Support
++++++++++++++++++++
+
+A set of functional tests for verification of RX checksum calculation for tunneled traffic.
+Open vSwitch enables RX checksum offloading by default if NIC supports it. It is to note,
+that it is not possible to disable or enable RX checksum offloading. In order to verify
+correct RX checksum calculation in software, user has to execute these testcases
+at NIC without HW offloading capabilities.
+
+Testcases utilize existing overlay physical to physical (op2p) network deployment
+implemented in vsperf. This deployment expects, that traffic generator sends unidirectional
+tunneled traffic (e.g. vxlan) and Open vSwitch performs data decapsulation and sends them
+back to the traffic generator via second port.
+
+======================================== ======================================================================================
+Testcase Name                            Description
+======================================== ======================================================================================
+ovsdpdk_checksum_l3                      Test verifies RX IP header checksum (offloading) validation for
+                                         tunneling protocols.
+ovsdpdk_checksum_l4                      Test verifies RX UDP header checksum (offloading) validation for
+                                         tunneling protocols.
+======================================== ======================================================================================
+
+Flow Control Support
+++++++++++++++++++++
+
+A set of functional testcases for the validation of flow control support in Open vSwitch
+with DPDK support. If flow control is enabled in both OVS and Traffic Generator,
+the network endpoint (OVS or TGEN) is not able to process incoming data and
+thus it detects a RX buffer overflow. It then sends an ethernet pause frame (as defined at 802.3x)
+to the TX side. This mechanism will ensure, that the TX side will slow down traffic transmission
+and thus no data is lost at RX side.
+
+Introduced testcases use physical to physical scenario to forward data between
+traffic generator ports. It is expected that the processing of small frames in OVS is slower
+than line rate. It means that with flow control disabled, traffic generator will
+report a frame loss. On the other hand with flow control enabled, there should be 0%
+frame loss reported by traffic generator.
