Functional tests ran on:
- NIC: ConnectX-4 Lx / OS: Ubuntu 20.04 LTS / Driver: MLNX_OFED_LINUX-5.5-1.0.3.2 / Firmware: 14.32.1010
- NIC: ConnectX-4 Lx / OS: Ubuntu 20.04 LTS / Kernel: 5.16.0-rc5 / Driver: rdma-core v38.0 / Firmware: 14.32.1010
- NIC: ConnectX-5 / OS: Ubuntu 20.04 LTS / Driver: MLNX_OFED_LINUX-5.5-1.0.3.2 / Firmware: 16.32.1010
- NIC: ConnectX-5 / OS: Ubuntu 20.04 LTS / Kernel: 5.16.0-rc5 / Driver: v38.0 / Firmware: 16.32.1010
- NIC: ConnectX-6 Dx / OS: Ubuntu 20.04 LTS / Driver: MLNX_OFED_LINUX-5.5-1.0.3.2 / Firmware: 22.32.1010

Compilation tests with multiple configurations in the following OS/driver combinations are also passing:
- Ubuntu 20.04.3 with MLNX_OFED_LINUX-5.5-1.0.3.2.
- Ubuntu 20.04.3 with rdma-core master (c52b43e).
- Ubuntu 20.04.3 with rdma-core v28.0.
- Ubuntu 18.04.6 with rdma-core v17.1.
- Ubuntu 18.04.6 with rdma-core master (c52b43e) (i386).
- Ubuntu 16.04.7 with rdma-core v22.7.
- Fedora 35 with rdma-core v38.0.
- Fedora 36 (Rawhide) with rdma-core v38.0
- CentOS 7 7.9.2009 with rdma-core master (940f53f).
- CentOS 7 7.9.2009 with MLNX_OFED_LINUX-5.5-1.0.3.2.
- CentOS 8 8.4.2105 with rdma-core master (940f53f).
- OpenSUSE Leap 15.3 with rdma-core v31.0.
- Windows Server 2019 with Clang 11.0.0.

The only issue we found that was introduced by 20.11.4-rc1 is the following:
- Bug 916 - [20.11.4-rc1][mlx5] 2% single core packet forwarding performance degradation (https://bugs.dpdk.org/show_bug.cgi?id=916)
We are still discussing whether we want to backport a fix to this release or not.

Thanks,
Ali
