+Release Notes
+=============
+
+Changes in |csit-release|
+-------------------------
+
+#. VPP PERFORMANCE TESTS
+
+ - **AF_XDP**: Added af_xdp driver support for all test cases. Test
+ results will be added in sub-sequent CSIT-2106 report.
+
+ - **GTPU tunnel**: Added GTPU HW Offload IPv4 routing tests.
+
+ - **Intel Xeon Ice Lake**: Added initial test data for these
+ platforms. Current CSIT-2106 report data for Intel Xeon Ice Lake
+ comes from an external source (Intel labs running CSIT code on
+ "8360Y D Stepping" and "6338N" processors). For details about the
+ physical setup see :ref:`tested_physical_topologies`. Tested
+ VPP and CSIT versions are pre-release, VPP
+ 21.06-rc0~779-gd640ae52f.
+
+ - **MLRsearch improvements**: Added support for multiple packet
+ throughput rates in a single search, each rate is associated
+ with a distinct Packet Loss Ratio (PLR) criterion. Previously
+ only Non Drop Rate (NDR) (PLR=0) and single Partial Drop Rate
+ (PDR) (PLR<0.5%) were supported. Implemented number of
+ optimizations improving rate discovery efficiency.
+
+ - **Reduction of tests**: Removed obsolete VPP use cases and
+ superfluous test combinations from continuous and report test
+ executions, including:
+
+ - All vts tests, obsolete use cases.
+ - dot1q tests apart from dot1q-l2bd, superfluous combinations.
+ - -100flows, -100kflows in all acl tests.
+ - nat44 tests
+
+ - -pps tests, replaced by -tput tests.
+ - h1-p1-s1 single session tests, unessential combination.
+ - h4096-p63-s258048 tests, unessential scale combination.
+
+ - ipsec tests
+
+ - ethip4ipsectptlispgpe.
+ - policy-aes128gcm.
+ - policy-aes128cbc-hmac256sha.
+ - policy-aes128cbc-hmac512sha.
+ - int-aes128cbc-hmac256sha.
+ - scale of
+
+ - 400tnlsw.
+ - 5000tnlsw.
+ - 20000tnlsw.
+ - 60000tnlsw.
+
+#. TEST FRAMEWORK
+
+ - **Telemetry retouch**: Refactored telemetry retrieval from DUTs and
+ SUTs. Included VPP perfmon plugin telemetry with all perfmon
+ bundles available in VPP release.
+
+ - **Upgrade to Ubuntu 20.04 LTS**: Re-installed base operating system
+ to Ubuntu 20.04.2 LTS. Upgrade included also baseline Docker
+ containers used for spawning topology.
+
+ - **CSIT test environment** version has been updated to ver. 7, see
+ :ref:`test_environment_versioning`.
+
+ - **CSIT in AWS environment**: Added CSIT support for AWS c5n
+ instances environment. Test results will be added in sub-sequent
+ CSIT-2106 report.
+
+ - **CSIT PAPI support**: Due to issues with PAPI performance, VAT is
+ still used in CSIT for all VPP scale tests. See known issues
+ below.
+
+ - **General Code Housekeeping**: Ongoing code optimizations and bug
+ fixes.
+
+#. PRESENTATION AND ANALYTICS LAYER
+
+ - **Graphs improvements**: Updated Packet Latency graphs,
+ see :ref:`latency_methodology`.

+| # | JiraID | Issue Description |
++====+=========================================+===========================================================================================================+
+| 1 | `CSIT-1782 | Multicore AVF tests are failing when trying to create interface. |
+| | <https://jira.fd.io/browse/CSIT-1782>`_ | |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 2 | `CSIT-1763 | Adapt ramp-up phase of nat44 tests for different frame sizes. |
+| | <https://jira.fd.io/browse/CSIT-1763>`_ | Currently ramp-up phase rate and duration values are correctly set for tests with 64B frame size. |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 3 | `CSIT-1671 | All CSIT scale tests can not use PAPI due to much slower performance compared to VAT/CLI (it takes much |
+| | <https://jira.fd.io/browse/CSIT-1671>`_ | longer to program VPP). This needs to be addressed on the PAPI side. |
+| +-----------------------------------------+ The usual PAPI library spends too much time parsing arguments, so even with async processing (hundreds of |
+| | `VPP-1763 | commands in flight over socket), the VPP configuration for large scale tests (millions of messages) takes |
+| | <https://jira.fd.io/browse/VPP-1763>`_ | too long. |
++----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 4 | `CSIT-1789 | AVF driver does not perform RSS in a deterministic way. |
+| | <https://jira.fd.io/browse/CSIT-1789>`_ | This increases standard deviation of tests with small number of flows (mainly ipsec). |
