+Fixed

+
+Issues reported in previous releases which were fixed in this release:
+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
| # | JiraID | Issue Description |
+====+=========================================+===========================================================================================================+
-| 1 | `CSIT-1782 | Multicore AVF tests are failing when trying to create interface. The issue persists after FVL FW upgrade. |
-| | <https://jira.fd.io/browse/CSIT-1782>`_ | |
+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
-| 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. |
+| 1 | `CSIT-1789 | AVF driver does not perform RSS in a deterministic way. |
+| | <https://jira.fd.io/browse/CSIT-1789>`_ | VPP now uses the same RSS key with AVF driver as with DPDK driver. |
+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
-| 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. |
+| 2 | `CSIT-1786 | IP4 and IP6 scale tests failing with no traffic forwarded. |
+| | <https://jira.fd.io/browse/CSIT-1786>`_ | CSIT replaced the old single VAT command by file full of "exec" CLI commands executed by VAT. |
+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
-| 4 | `CSIT-1789 | AVF driver does not perform RSS in a deterministic way. |
-| | <https://jira.fd.io/browse/CSIT-1789>`_ | This increases standard deviation of tests with small number of flows (mainly ipsec). |

++====+=========================================+===========================================================================================================+
+| 3 | `CSIT-1782 | Multicore AVF tests are failing when trying to create interface. |
+| | <https://jira.fd.io/browse/CSIT-1782>`_ | Frequency is reduced by s CSIT workaround, but occasional failures do still happen. |
+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
-| 6 | `CSIT-1786 | IP4 and IP6 scale tests failing with no traffic forwarded. |
-| | <https://jira.fd.io/browse/CSIT-1786>`_ | Issue reported to VPP devs. |
+| 4 | `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. |
+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
-| 7 | `CSIT-1785 | NAT44ED tests failing to establish all TCP sessions. |
-| | <https://jira.fd.io/browse/CSIT-1785>`_ | |
+| 5 | `CSIT-1789 | IPSEC SW async scheduler tests show bad behavior. |
+| | <https://jira.fd.io/browse/CSIT-1789>`_ | VPP code is not behaving correctly when crypto workers are the bottleneck. |
+| +-----------------------------------------+ |
+| 5 | `VPP-1998 | |
+| | <https://jira.fd.io/browse/VPP-1998>`_ | |
+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
-| 8 | `CSIT-1791 | Performance regression in RDMA tests, due to CSIT environment changes. |
-| | <https://jira.fd.io/browse/CSIT-1791>`_ | |
+| 6 | `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>`_ | |
+----+-----------------------------------------+-----------------------------------------------------------------------------------------------------------+
+| 7 | `CSIT-1791 | Performance regression in RDMA tests, due to CSIT environment changes. |
+| | <https://jira.fd.io/browse/CSIT-1791>`_ | Two symptoms: 1. 10-20% regression across most tests. 2. DUT performance cap just below 38 Mpps. |
