Hello,

We ran the following functional tests with Nvidia hardware on v20.11.7-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:
  Items:
  - eth
  - geneve
  - gre
  - gre_key
  - gtp

  - mark
  - meta
  - mpls
  - nvgre
  - tag

- 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:
- NIC: ConnectX-4 Lx / OS: Ubuntu 20.04 LTS / Driver: MLNX_OFED_LINUX-5.8-1.0.1.1 / Firmware: 14.32.1010
- NIC: ConnectX-5 / OS: Ubuntu 20.04 LTS / Driver: MLNX_OFED_LINUX-5.8-1.0.1.1 / Firmware: 16.35.1012
- NIC: ConnectX-6 Dx / OS: Ubuntu 20.04 LTS / Driver: MLNX_OFED_LINUX-5.8-1.0.1.1 / Firmware: 22.35.1012
- DPU: BlueField-2 / DOCA SW version: 1.5.0 / Firmware: 24.35.1012

Additionally, we ran compilation tests with multiple configurations in the following OS/driver combinations:
- Ubuntu 22.04.1 with MLNX_OFED_LINUX-5.8-1.1.2.1.
- Ubuntu 20.04.5 with MLNX_OFED_LINUX-5.8-1.1.2.1.
- Ubuntu 20.04.5 with rdma-core master (76cfaa1).
- Ubuntu 20.04.5 with rdma-core v28.0.
- Ubuntu 18.04.6 with rdma-core v17.1.
- Ubuntu 18.04.6 with rdma-core master (76cfaa1) (i386).
- Ubuntu 16.04.7 with rdma-core v22.7.
- Fedora 37 with rdma-core v41.0.
- Fedora 38 (Rawhide) with rdma-core v41.0.
- CentOS 7 7.9.2009 with rdma-core master (76cfaa1).
- CentOS 7 7.9.2009 with MLNX_OFED_LINUX-5.8-1.0.1.1.
- CentOS 8 8.4.2105 with rdma-core master (76cfaa1).
- OpenSUSE Leap 15.4 with rdma-core v38.1.
- Windows Server 2019 with Clang 11.0.0.

The builds are passing except for debug builds on Fedora with gcc 12:
lib/librte_ring/rte_ring_elem.h:194:25: error: 'memcpy' reading 32 bytes from a region of size 4 [-Werror=stringop-overread]

Please note that not all the functional tests mentioned above fall under "Basic functionality with testpmd" like reported in the release notes for previous releases:
https://git.dpdk.org/dpdk-stable/commit/?h=v20.11.6&id=73655c6414914c99a33010e9e7bdae9cafd24404
Some of them test other example apps.

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

Thanks,
Ali
