+    // Alternative Note for 1st Bullet when bad microcode Skx, Clx results are published
+    note::
+    L3fwd throughput drop in the current release in comparison to previous
+    releases **on Intel Xeon 2n-skx, 3n-skx and 2n-clx testbeds**: L3fwd
+    performance test data shows lower performance and behaviour
+    inconsistency of these systems following the recent 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 corrected in subsequent maintenance report
+    version(s) once the issue is resolved. See :ref:`vpp_known_issues`.
