Release Notes
=============
- CSIT test environment is versioned, see
:ref:`test_environment_versioning`.
- - **GENEVE tests**: Added VPP performance tests for GENEVE tunnels.
-
- - See :ref:`geneve_methodology` for more details.
-
- - **NAT44 tests**: Added new test type, pure throughput tests.
- They are similar to PPS tests, but they employ ramp-up trials
- to ensure all sessions are created (and not timing out)
- for performance trials.
+ - **Upgrade to Ubuntu 20.04 LTS**: Reinstall base operating system to
+ Ubuntu 20.04.2 LTS. Upgrade includes also baseline Docker
+ containers used for spawning topology.
- - **Jumbo for ipsec**: Test cases with 9000 byte frames are re-enabled
- in ipsec suites.
+ - Initial test data for Intel Xeon Ice Lake platforms. Current
+ CSIT-2106 report data for Intel Xeon Ice Lake comes from an
+ external source (Intel labs running CSIT code on 8360Y D Stepping
+ and 6338N processors). For detail about the physical setup
+ see :ref:`tested_physical_topologies`. Tested VPP and CSIT
+ versions are pre-release, VPP 21.06-rc0~779-gd640ae52f.
- - **Randomized profiles**: Improved repeatability and cycle length.
- For details, see :ref:`packet_flow_ordering`.
+ - **AF_XDP**: Added af_xdp driver testing for all testcases.
- - **Arm 2n-tx2 testbed**: New physical testbed type installed in
- FD.io CSIT, with VPP and DPDK performance data added to CSIT
- trending and this report.
+ - **GTPU tunnel**: Added GTPU HW Offload IPv4 routing tests.
- - **Framework speedup**: Shortened overall test job duration
- by using a different test selection mechanism (using --test
- instead of --include) and by avoiding unnecessary PAPI reconnects.
+ - **Telemetry retouch**: Redesign telemetry retrieval from DUT.
+ Include VPP perfmon plugin telemetry.
#. TEST FRAMEWORK
- - **TRex ASTF**: Improved capability to run TRex in advanced stateful mode.
-
- **CSIT PAPI support**: Due to issues with PAPI performance, VAT is
still used in CSIT for all VPP scale tests. See known issues below.

+====+=========================================+===========================================================================================================+
-| 1 | `CSIT-570 | Sporadic (1 in 200) NDR discovery test failures on x520. DPDK reporting rx-errors, indicating L1 issue. |
-| | <https://jira.fd.io/browse/CSIT-570>`_ | Suspected issue with HW combination of X710-X520 in LF testbeds. Not observed outside of LF testbeds. |

-| 2 | `VPP-662 | 9000B packets not supported by NICs VIC1227 and VIC1387. |
-| | <https://jira.fd.io/browse/VPP-662>`_ | |
+| 1 | `CSIT-1782 | Multicore AVF tests are failing when trying to create interface. |

+| 2 | `CSIT-1763 | Adapt ramp-up phase of nat44 tests for different frame sizes. |
| | <https://jira.fd.io/browse/CSIT-1763>`_ | Currently ramp-up phase rate and duration values are correctly set for tests with 64B frame size. |

+| 3 | `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. |
| +-----------------------------------------+ The usual PAPI library spends too much time parsing arguments, so even with async processing (hundreds of |
| | `VPP-1763 | commands in flight over socket), the VPP configuration for large scale tests (millions of messages) takes |
| | <https://jira.fd.io/browse/VPP-1763>`_ | too long. |
+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
-| 5 | `VPP-1934 | [i40e] Interfaces are not brought up from carrier-down. |
-| | <https://jira.fd.io/browse/VPP-1934>`_ | In case of i40e -based interface (e.g Intel x700 series NIC) is bound to kernel driver (i40e) and is in |
-| | | state "no-carrier" (<NO-CARRIER,BROADCAST,MULTICAST,UP>) because previously it was disabled via |
-| | | "I40E_AQ_PHY_LINK_ENABLED" call, then VPP during initialization of AVF interface is not re-enabling |
-| | | interface link via i40e driver to up. |
-| | | CSIT implemented `workaround for AVF interface <https://gerrit.fd.io/r/c/csit/+/29086>`_ until fixed. |
