 Changes in |csit-release|
 -------------------------
 
+#. DPDK PERFORMANCE TESTS
+
+   - **Intel Xeon 2n-skx, 3n-skx and 2n-clx testbeds**: Testpmd and
+     L3fwd performance test data is not included in this report
+     version. This is due to the lower performance and behaviour
+     inconsistency of these systems following the upgrade of processor
+     microcode packages (skx ucode 0x2000064, clx ucode 0x500002c) as
+     part of updating Ubuntu 18.04 LTS kernel version. Tested VPP and
+     DPDK applications (L3fwd) are affected. Skx and Clx test data
+     will be added in subsequent maintenance report version(s) once
+     the issue is resolved. See :ref:`dpdk_known_issues`.

 #. DPDK RELEASE VERSION CHANGE
 
    - |csit-release| tested |dpdk-release|, as used by |vpp-release|.
 
+#. TEST ENVIRONMENT
+
+   - **TRex Fortville NIC Performance**: Received FVL fix from Intel
+     resolving TRex low throughput issue. TRex per FVL NIC throughput
+     increased from ~27 Mpps to the nominal ~37 Mpps. For detail see
+     `CSIT-1503 <https://jira.fd.io/browse/CSIT-1503>`_ and `TRex-519
+     <https://trex-tgn.cisco.com/youtrack/issue/trex-519>`_].
+
+   - **New Intel Xeon Cascadelake Testbeds**: Added performance tests
+     for 2-Node-Cascadelake (2n-clx) testbeds with x710, xxv710 and
+     mcx556a-edat NIC cards.
+
+..
+    // Alternative Note for 1st Bullet when bad microcode Skx, Clx results are published
+    - **Intel Xeon 2n-skx, 3n-skx and 2n-clx testbeds**: Testpmd and
+      L3fwd performance test data is included in this report version,
+      but it shows lower performance and behaviour inconsistency of
+      these systems following the upgrade of processor microcode
+      packages (skx ucode 0x2000064, clx ucode 0x500002c) as part of
+      updating Ubuntu 18.04 LTS kernel version. Tested VPP and DPDK
+      applications (L3fwd) are affected. Skx and Clx test data will be
+      corrected in subsequent maintenance report version(s) once the
+      issue is resolved. See :ref:`vpp_known_issues`.
