Subject: [net-next 04/11] net/mlx5e: SHAMPO: Improve hw gro capability checking
Date: Thu, 16 Jan 2025 13:55:22 -0800	[thread overview]
Message-ID: <20250116215530.158886-5-saeed@kernel.org> (raw)
In-Reply-To: <20250116215530.158886-1-saeed@kernel.org>

From: Saeed Mahameed <saeedm@nvidia•com>

Add missing HW capabilities, declare the feature in
netdev->vlan_features, similar to other features in mlx5e_build_nic_netdev.
No functional change here as all by default disabled features are
explicitly disabled at the bottom of the function.
