 #. VPP PERFORMANCE TESTS
 
+   - **Regressions with DPDK drivers**: Change from DPDK v21.08 to DPDK
+     v21.11 introduced regression across all tests using dpdk
+     drivers (with dpdk_plugin loaded). Compared to previous VPP
+     release performance drop varies in the range of -15% to -6%,
+     depending on test. It is related to updated MTU checks within
+     DPDK code and associated VPP code changes. See
+     `VPP v2202 release notes <https://s3-docs.fd.io/vpp/22.02/aboutvpp/releasenotes/v22.02.html>`_
+     and :ref:`vpp_known_issues`.
+
+   - **Number of CSIT 9000B frame tests failing**: tests with higher
+     encapsulation overhead are failing due to exceeding default
+     Ethernet Maximum Frame Size value that has been reduced by MTU
+     related VPP code changes. See
