Subject: [PATCH net-next V2 01/10] net/mlx5: IFC updates for SF max IO EQs
Date: Mon, 8 Jul 2024 11:00:16 +0300	[thread overview]
Message-ID: <20240708080025.1593555-2-tariqt@nvidia.com> (raw)
In-Reply-To: <20240708080025.1593555-1-tariqt@nvidia.com>

From: Daniel Jurgens <danielj@nvidia.com>

Expose a new cap sf_eq_usage. The vhca_resource_manager can write this
cap, indicating the SF driver should use max_num_eqs_24b to determine
how many EQs to use.
