+ - **Added Wireguard tests** for VPP software path (3n-icx, 3n-snr
+ testbeds) and with built-in HW crypto QAT device (3n-snr testbed
+ only).

+| 1 | `CSIT-1671 | All CSIT scale tests can not use PAPI due to much slower performance compared to VAT/CLI (it takes much |
| | `_ | 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. |
| | `_ | More improvements needed to achieve sufficient configuration speed. |

-| 7 | `CSIT-1791 | Performance regression in RDMA tests, due to CSIT environment changes. |
