-Release Notes
-=============
-
-Changes in |csit-release|
--------------------------
-
-#. VPP PERFORMANCE TESTS
-
- - **Added new performance testbed 3n-snr** (3 Node SnowRidge, with Intel
- Atom processors), to later replace 3n-dnv and 2n-dnv (3 and 2 Node
- Denverton) testbeds.
-
- - **Added GTPU HW offload tests** using VPP GTPU hardware offload
- with Intel e810 4p25ge NICs (3n-icx testbeds only). These tests
- were already there in CSIT-2206, but were yielding invalid
- results due to using TRex v2.97 that was incompatible with e810
- NICs used for those tests.
-
- - **Added Wireguard tests** using VPP software crypto (3n-icx, 3n-snr
- testbeds) and using built-in hardware crypto QAT device (3n-snr testbed
- only).
-
- - **Reduction of tests**: Removed certain test variations executed
- iteratively for the report (as well as in daily and weekly
- trending) due to physical testbeds overload.
-
-#. TEST FRAMEWORK
-
- - CSIT-2210 executes all VPP v22.10 performance tests using vpp ubuntu2204
- images, due to CSIT execution environment change as noted below. This
- applies to all performance testbeds except Denverton. Consequently, VPP
- v22.06 has not been re-tested in CSIT-2210 environment, as no ubuntu204
- images are available for that VPP version. Performance comparison
- between VPP v22.10 (current version) vs VPP v22.06 (previous version)
- may be impacted by VPP build environment change (ubuntu2004 to ubuntu
- 2204) change and CSIT environment change. See :ref:`vpp_rca` for
- details.
-
- - **CSIT test environment** version has been updated to ver. 11, see
- :ref:`test_environment_versioning`.
-
- - **TCP TPUT profiles** had to be changed, as newer TRex versions
- are not deterministic enough when deciding when to send an ACK.
-
- - **CSIT PAPI support**: Due to issues with PAPI performance, and
- deprecation of VAT, VPP CLI is used in CSIT for many VPP scale
- tests. See :ref:`vpp_known_issues`.
-
- - **General Code Housekeeping**: Ongoing code optimizations and bug
- fixes.
-
-#. PRESENTATION AND ANALYTICS LAYER
-
- - **C-Dash** `performance dashboard <http://csit.fd.io/>`_ got updated UI and
- updated backend increasing its performance and robustness.

-| # | JiraID | Issue Description |
-+====+=========================================+===========================================================================================================+
-| 1 | `CSIT-1671 | All CSIT scale tests can not use PAPI due to much slower performance compared to VAT/CLI (it takes much |
-| | <https://jira.fd.io/browse/CSIT-1671>`_ | longer to program VPP). This needs to be addressed on the PAPI side. |
-| +-----------------------------------------+ Currently, the time critical code uses VAT running large files with exec statements and CLI commands. |
-| | `VPP-1763 | Still, we needed to reduce the number of scale tests run to keep overall duration reasonable. |
-| | <https://jira.fd.io/browse/VPP-1763>`_ | More improvements needed to achieve sufficient configuration speed. |
-+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
-| 2 | `CSIT-1782 | Multicore AVF tests are failing when trying to create interface. |
-| | <https://jira.fd.io/browse/CSIT-1782>`_ | Frequency is reduced by CSIT workaround, but occasional failures do still happen. |
-+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
-| 3 | `CSIT-1785 | NAT44ED tests failing to establish all TCP sessions. |
-| | <https://jira.fd.io/browse/CSIT-1785>`_ | At least for max scale, in allotted time (limited by session 500s timeout) due to worse |
-| +-----------------------------------------+ slow path performance than previously measured and calibrated for. |
-| | `VPP-1972 | CSIT removed the max scale NAT tests to avoid this issue. |
-| | <https://jira.fd.io/browse/VPP-1972>`_ | |
-+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
-| 4 | `CSIT-1799 | All NAT44-ED 16M sessions CPS scale tests fail while setting NAT44 address range. |
-| | <https://jira.fd.io/browse/CSIT-1799>`_ | |
-+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
-| 5 | `CSIT-1800 | All Geneve L3 mode scale tests (1024 tunnels) are failing. |
-| | <https://jira.fd.io/browse/CSIT-1800>`_ | |
-+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
-| 6 | `CSIT-1801 | 9000B payload frames not forwarded over tunnels due to violating supported Max Frame Size (VxLAN, LISP, |
-| | <https://jira.fd.io/browse/CSIT-1801>`_ | SRv6). |
-+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
-| 7 | `CSIT-1802 | AF-XDP - NDR tests failing from time to time. |
-| | <https://jira.fd.io/browse/CSIT-1802>`_ | |
-+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
-| 8 | `CSIT-1804 | All testbeds: NDR tests failing from time to time. |
-| | <https://jira.fd.io/browse/CSIT-1804>`_ | |
-+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
-| 9 | `CSIT-1808 | All tests with 9000B payload frames not forwarded over memif interfaces. |
-| | <https://jira.fd.io/browse/CSIT-1808>`_ | |
-+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
-| 10 | `CSIT-1827 | 3n-icx, 3n-skx: all AVF crypto tests sporadically fail. 1518B with no traffic, IMIX with excessive |
-| | <https://jira.fd.io/browse/CSIT-1827>`_ | packet loss. |
-+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
-| 11 | `CSIT-1835 | 3n-icx: vppecho BPS tests failing on timeout when checking hoststack finished. |
-| | <https://jira.fd.io/browse/CSIT-1835>`_ | |
-+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
-| 12 | `CSIT-1849 | 2n-skx, 2n-clx, 2n-icx: UDP 16m TPUT tests fail to create all sessions. |
-| | <https://jira.fd.io/browse/CSIT-1849>`_ | |

-| 1 | `CSIT-1834 | 2n-icx, 2n-skx: sporadic AVF soak tests failing to find critical load with PLRsearch. |
-| | <https://jira.fd.io/browse/CSIT-1834>`_ | |

-| 3 | `CSIT-1851 | trending regression: various icelake tests around 2202-04-15 |
-| | <https://jira.fd.io/browse/CSIT-1851>`_ | Somewhat expected consequence of a VPP usability fix, |
-| | | the previous VPP compiler version was too new for the OS used. |

-| | <https://jira.fd.io/browse/CSIT-1852>`_ | Old issue, only now distinguished from CSIT-1751. |

-| | <https://jira.fd.io/browse/CSIT-1853>`_ | VPP change added more computation to slow path (in order to support multiple VRFs). |
-| | | Not clear if the VPP implementation is optimized enough. |
