 #. VPP PERFORMANCE TESTS
 
-   - **Intel Xeon 2n-skx, 3n-skx and 2n-clx testbeds**: VPP 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), done 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:`vpp_known_issues`.
