Subject: [PATCH v2 0/2] net/mlx5: improvements to link status handling
Date: Fri, 30 Oct 2026 18:28:41 +0100 [thread overview]
Message-ID: <20261030172843.2304296-1-dsosnowski@nvidia.com> (raw)
In-Reply-To: <20261026160400.1290443-1-dsosnowski@nvidia.com>
This series is a result of splitting patch:
https://patches.dpdk.org/project/dpdk/patch/20261026160400.1290443-1-dsosnowski@nvidia.com/
Patch 1 - Fix for mlx5 link update function to query current link carrier status,
bypassing the delay introduced by linkwatch in Linux kernel.
Patch 2 - Move to link status polling, in place of relying on netlink events
which can be delayed by linkwatch for up to 1s.
