[PATCH 20.11 0/3] net/mlx5: fix link state detection

[Dmitry Kozlyuk]

[ backport of https://inbox.dpdk.org/dev/20220301121514.41497-1-dkozlyuk@nvidia.com ]

This patchset fixes two related issues:
* In rare occasions with any HW link state change to UP was missed.
* If a port was DOWN before startup, its netdev would come UP,
  but appear DOWN in DPDK (especially probable with ConnectX-4).

Dmitry Kozlyuk (3):
  common/mlx5: add Netlink event helpers
  net/mlx5: fix link status change detection
  net/mlx5: fix initial link status detection
