Hello,

We ran the following functional tests with Nvidia hardware on v23.11.5-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
(https://doc.dpdk.org/guides/nics/mlx5.html#supported-hardware-offloads)
- 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.
- Buffer Split tests.
- Tx scheduling tests.

Functional tests ran on:
- NIC: ConnectX-6 Dx / OS: Ubuntu 22.04 / Driver:
MLNX_OFED_LINUX-23.10-5.1.4.0 / Firmware: 22.39.5050
- NIC: ConnectX-7 / OS: Ubuntu 22.04 / Driver:
MLNX_OFED_LINUX-23.10-5.1.4.0 / Firmware: 28.39.5050
- DPU: BlueField-2 / DOCA SW version: 2.5.4 / Firmware: 24.39.5050

Additionally, we ran build tests with multiple configurations on the
following OS/driver combinations (all passed):
- Debian 12 with MLNX_OFED_LINUX-24.10-3.2.5.0.
- Ubuntu 22.04 with MLNX_OFED_LINUX-24.10-3.2.5.0.
- Ubuntu 24.04 with MLNX_OFED_LINUX-24.10-3.2.5.0.
- Ubuntu 22.04 with rdma-core master (091ddb5).
- Ubuntu 24.04 with rdma-core v50.0.
- Fedora 42 with rdma-core v55.0.
- Fedora 43 (Rawhide) with rdma-core v58.0.
- OpenSUSE Leap 15.6 with rdma-core v49.1.
- Windows Server 2022 with Clang 18.1.8.

We don't see new issues caused by the changes in this release.

Thanks,
Ali
