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