Subject: [PATCH 19.11 0/3] net/mlx5: fix link state detection
Date: Fri, 11 Mar 2022 10:06:24 +0200 [thread overview]
Message-ID: <20220311080627.1195847-1-dkozlyuk@nvidia.com> (raw)
[ 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
