Hello,

We ran the following list of test suites on NVIDIA hardware with v25.07-rc3:

- 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 testing.
- VLAN filtering, stripping and insertion tests.
- Checksum and TSO tests.
- ptype reporting.
- link status interrupt using the example application link_status_interrupt tests.
- Interrupt mode using l3fwd-power example application tests.
- Multi process testing using multi process example applications.
- Hardware LRO tests.
- Buffer Split.
- Tx scheduling.

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

Thanks,
Ali
