 #. 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.

-         - 400tnlsw.
-         - 5000tnlsw.
-         - 20000tnlsw.
-         - 60000tnlsw.
+   - **Regressions with DPDK drivers**: Change from DPDK v21.08 to DPDK
+     v21.11 introduced regression across all tests using dpdk
+     drivers (with dpdk_plugin loaded). Compared to previous VPP
+     release performance drop varies in the range of -15% to -6%,
+     depending on test. It is related to updated MTU checks within
+     DPDK code and associated VPP code changes. See
+     `VPP v2202 release notes <https://s3-docs.fd.io/vpp/22.02/aboutvpp/releasenotes/v22.02.html>`_
+     and :ref:`vpp_known_issues`.
+
+   - **Number of CSIT 9000B frame tests failing**: tests with higher
+     encapsulation overhead are failing due to exceeding default
+     Ethernet Maximum Frame Size value that has been reduced by MTU
+     related VPP code changes. See
+     `VPP v2202 release notes <https://s3-docs.fd.io/vpp/22.02/aboutvpp/releasenotes/v22.02.html>`_
+     and :ref:`vpp_known_issues`.
+
+   - **Intel Xeon Ice Lake**: Performance test data for these platforms
+     is now provided by testbeds newly installed in FD.io CSIT labs.
+     For details about the physical setup see
+     :ref:`physical_testbeds_2n_icx` and
+     :ref:`physical_testbeds_3n_icx`.
+
+   - **Reduction of tests**: Removed certain test variations executed
+     iteratively for the report (as well as in daily and weekly
+     trending) due to physical testbeds overload.
+
+   - **RC2 coverage test data is used for 2n-icx test bed**: There is only
+     one 2n-icx test bed and the amount of tests is large (same as 2n-skx with 4
+     test beds), so we decided to use test data already available from RC2
+     testing.
 
 #. 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.
-
-   - **TRex upgrade v2.86 to v2.88**: Included move to DPDK 21.02 and
-     changed the way egress low latency queues are used in FVL NICs.
-     This broke latency measurements for majority of FVL NICs in
-     CSIT. Latency values look better after upgrading FVL FW on TRex
-     servers, but still somewhat higher than before the TRex upgrade.
-     Tracked by `CSIT-1790 <https://jira.fd.io/browse/CSIT-1790>`_.
-
-   - **CSIT test environment** version has been updated to ver. 7, see
+   - **CSIT test environment** version has been updated to ver. 10, 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.
+   - **CSIT PAPI support**: Due to issues with PAPI performance, and
+     deprecation of VAT, VPP CLI is used in CSIT for many VPP scale
+     tests. See :ref:`vpp_known_issues`.
 
    - **General Code Housekeeping**: Ongoing code optimizations and bug
