We ran the following tests on Mellanox hardware for this version:
- Basic functionality:
  Send and receive multiple types of traffic.
- testpmd xstats counter tests.
- testpmd timestamp tests.
- Changing/checking link status through testpmd.
- RTE flow and flow_director tests:
  Items: eth / vlan / ipv4 / ipv6 / tcp / udp / gre
  Actions: drop / queue / rss / mark / flag
- Some RSS tests.
- VLAN stripping and insertion tests.
- Checksum and TSO tests.
- ptype tests.
- l3fwd-power example application tests.
- Multi-process example applications tests.

Testing matrix:
- NIC: ConnectX-4 Lx / OS: RHEL7.4 / Driver: MLNX_OFED_LINUX-5.0-2.1.8.0 / Firmware: 14.27.1016
- NIC: ConnectX-5 / OS: RHEL7.4 / Driver: MLNX_OFED_LINUX-5.0-2.1.8.0 / Firmware: 16.27.2008

We found 2 issues:
- Failure to restart ports with kernels newer than 5.6 (call to mmap failed on UAR for txq).
- Applications fail to start with CONFIG_RTE_LIBRTE_MLX5_DEBUG enabled (mlx5_ifindex: Assertion `priv->if_index' failed).
We are discussing these issues internally, and we see no other regressions blocking the release.

Regards,
Ali
