Subject: [PATCH 12/13] net/mlx5e: Properly disable vlan strip on non-UL reps
Git-commit: f37044fd759b6bc40b6398a978e0b1acdf717372
References: git-fixes
Patch-mainline: v6.0-rc3
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")
