Subject: [PATCH net-next 09/15] net/mlx5e: Set page_pool order based on calculated page_shift
Date: Mon, 23 Feb 2026 22:41:49 +0200 [thread overview]
Message-ID: <20260223204155.1783580-10-tariqt@nvidia.com> (raw)
In-Reply-To: <20260223204155.1783580-1-tariqt@nvidia.com>
From: Dragos Tatulea <dtatulea@nvidia.com>
Instead of unconditionally setting the page_pool to 0, calculate it from
page_shift for MPWQE case.
