 Hello,

Apologies for the last-minute reply.

We ran the following functional tests with Nvidia hardware on v20.11.9-rc1:
- Basic functionality:
  Send and receive multiple types of traffic.
- testpmd xstats counter test.
- testpmd timestamp test.
- Changing/checking link status through testpmd.
- rte_flow tests.
- Some RSS tests.
- VLAN filtering, stripping and insertion tests.
- Checksum and TSO tests.
- ptype tests.
- link_status_interrupt example application tests.
- l3fwd-power example application tests.
- Multi-process example applications tests.
- Hardware LRO tests.

Functional tests ran on these cards:
- NIC: ConnectX-6 Dx / OS: Ubuntu 20.04 / Driver: MLNX_OFED_LINUX-23.04-1.1.3.0 / Firmware: 22.37.1014
- NIC: ConnectX-7 / OS: Ubuntu 20.04 / Driver: MLNX_OFED_LINUX-23.04-1.1.3.0 / Firmware: 28.37.1014
- DPU: BlueField-2 / DOCA SW version: 2.0.2 / Firmware: 24.37.1300

Build tests (all passed):
- Ubuntu 20.04.6 with MLNX_OFED_LINUX-23.04-1.1.3.0.
- Ubuntu 20.04.6 with rdma-core master (aba30bd).
- Ubuntu 20.04.6 with rdma-core v28.0.
- Ubuntu 18.04.6 with rdma-core master (aba30bd) (i386).
- Fedora 38 with rdma-core v44.0.
- Fedora 39 (Rawhide) with rdma-core v46.0.
- OpenSUSE Leap 15.5 with rdma-core v42.0.
- Windows Server 2019 with Clang 11.0.0.

We see warnings while restarting ports in testpmd application if MPRQ is enabled, and we think it's caused by this backported change:
net/mlx5: fix MPRQ stride size to accommodate the headroom (https://git.dpdk.org/dpdk-stable/commit/?h=81002988e01)
This is the only issue we found that might've been caused by changes in this release. Hope I can update by tomorrow.

We're investigating some internal test failures that were caused by environment changes, but we have a high pass rate in our regression testing overall.

Thanks,
Ali
