#. 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`.
