Subject: [PATCH net-next 12/15] net/mlx5e: Add queue config ops for page size
Date: Mon, 23 Feb 2026 22:41:52 +0200 [thread overview]
Message-ID: <20260223204155.1783580-13-tariqt@nvidia.com> (raw)
In-Reply-To: <20260223204155.1783580-1-tariqt@nvidia.com>
From: Dragos Tatulea <dtatulea@nvidia.com>
For now allow only PAGE_SIZE. A subsequent patch will add support for
high order pages in zero-copy mode.
