-CSIT Release Notes
-==================
+Release Notes
+=============
 
-Changes in CSIT |release|
+Changes in |csit-release|
 -------------------------
 
-#. Improved performance of testpmd tests
+#. DPDK PERFORMANCE TESTS
 
-   - Performance of NICs - 2p40GE Intel xl710, 2p10GE Intel x710
+   - **Intel Xeon 2n-skx, 3n-skx 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) as part of updating Ubuntu 18.04
+     LTS kernel version. Tested VPP and DPDK applications (L3fwd) are
+     affected. Skx test data will be added in subsequent maintenance
+     report version(s) once the issue is resolved. See
+     :ref:`dpdk_known_issues`.
 
-#. Added L3FWD tests on 2p10GE Intel x520-DA2
+   - **Intel Xeon 2n-clx testbeds**: DPDK performance test data is now
+     included in this report, after resolving the issue of lower
+     performance and behaviour inconsistency of these systems due to
+     the Linux kernel driven upgrade of processor microcode packages
+     to 0x500002c. The resolution is to use latest SuperMicro BIOS 3.2
+     (for X11DPG-QT motherboards used) that upgrades processor
+     microcode to 0x500002c, AND NOT kernel provided ucode package as
+     it does put THE system into sub-optimal state.
+
+
+#. 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
+     cx556a-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`.
