Subject: [net 01/13] net/mlx5e: Properly disable vlan strip on non-UL reps
Date: Mon, 22 Aug 2022 12:59:05 -0700	[thread overview]
Message-ID: <20220822195917.216025-2-saeed@kernel.org> (raw)
In-Reply-To: <20220822195917.216025-1-saeed@kernel.org>

From: Vlad Buslov <vladbu@nvidia•com>

When querying mlx5 non-uplink representors capabilities with ethtool
rx-vlan-offload is marked as "off [fixed]". However, it is actually always
enabled because mlx5e_params->vlan_strip_disable is 0 by default when
initializing struct mlx5e_params instance. Fix the issue by explicitly
setting the vlan_strip_disable to 'true' for non-uplink representors.

Fixes: cb67b832921c ("net/mlx5e: Introduce SRIOV VF representors")
