+#. DPDK PERFORMANCE TESTS
+
+   - **Intel Xeon 2n-skx, 3n-skx and 2n-clx testbeds**: Testpmd and
+     L3fwd test data is not included in this report version. This is
+     due to performance and behaviour inconsistency following the
+     upgrade to the latest Ubuntu 18.04 LTS kernel version
+     (4.15.0-72-generic) and associated microcode packages (skx ucode
+     0x2000064, clx ucode 0x500002c). Test data will be added in
+     subsequent maintenance report version(s) once the issue is
+     resolved. See :ref:`dpdk_known_issues`.
