+ - **Intel Xeon 2n-skx, 3n-skx testbeds**: VPP performance test data
+ is not included in this report version. This is due to the lower
+ performance and behaviour inconsistency of these systems
+ following the upgrade of processor microcode packages (skx ucode
+ 0x2000064), done as part of updating Ubuntu 18.04 LTS kernel
+ version. Tested VPP and DPDK applications (L3fwd) are affected.
+ Skx test data will be added in subsequent maintenance report
+ version(s) once the issue is resolved. See
+ :ref:`vpp_known_issues`.
+
+ - **Intel Xeon 2n-clx testbeds**: VPP performance test data is now
+ included in this report, after resolving the issue of lower
+ performance and behaviour inconsistency of these systems due to
+ the Linux kernel driven upgrade of processor microcode packages
+ to 0x500002c. The resolution is to use latest SuperMicro BIOS 3.2
+ (for X11DPG-QT motherboards used) that upgrades processor
+ microcode to 0x500002c, AND NOT kernel provided ucode package as
+ it does put system into sub-optimal state. Subset of 2n-clx VPP
+ tests are failing due to clx system behaviour change: i) all ip4
+ tests with xxv710 and avf driver and ii) some cx556a rdma tests.
+ See :ref:`vpp_known_issues`.
+
+ - **Service density 2n-skx tests**: Added new NF density tests with
+ IPsec encryption between DUTs.
+
+ - **AVF tests**: Full test coveraged based on code changes in CSIT
+ core layer (driver/interface awareness) and generated by suite
+ generator (Intel Fortville NICs only).
+
+ - **Hoststack tests**: Major refactor of VPP Hoststack TCP/IP
+ performance tests using WRK generator talking to the VPP HTTP
+ static server plugin measuring connections per second and
+ requests per second. Added new iperf3 with LDPreload tests,
+ iperf3/LDPreload tests with packet loss induced via the VPP NSIM
+ (Network Simulator) plugin, and QUIC/UDP/IP transport tests.
+ All of the new tests measure goodput through the VPP Hoststack
+ from client to server.
+
+ - **Latency HDRHistogram**: Added High Dynamic Range Histogram
+ latency measurements based on the new capability in TRex traffic
+ generator. HDRH latency data presented in latency packet
+ percentile graphs and in detailed results tables.
+
+ - **Mellanox CX556A-EDAT tests**: Added tests with Mellanox
+ ConnectX5-2p100GE NICs in 2n-clx testbeds using VPP native rdma
+ driver.
+
+ - **IPsec reconfiguration tests**: Added tests measuring the impact
+ of IPsec tunnels creations and removals.
+
+ - **Load Balancer tests**: Added VPP performance tests for Maglev,
+ L3DSR (Direct Server Return), Layer 4 Load Balancing NAT Mode.
