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`.
