#. 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
