Subject: [PATCH net-next V5 14/15] net/mlx5: qos: Enable cross-device scheduling
Date: Tue, 20 Jan 2026 09:57:57 +0200 [thread overview]
Message-ID: <1768895878-1637182-15-git-send-email-tariqt@nvidia.com> (raw)
In-Reply-To: <1768895878-1637182-1-git-send-email-tariqt@nvidia.com>
From: Cosmin Ratiu <cratiu@nvidia.com>
Enable the new devlink feature.
All rate nodes will be stored in the shared device, when available.
The shared instance lock will additionally be acquired by all rate
manipulation code to protect against concurrent execution across
different functions of the same physical device.
