[PATCH 5.10 25/86] net/mlx5e: Properly disable vlan strip on non-UL reps

[Greg Kroah-Hartman]

From: Vlad Buslov <vladbu@xxxxxxxxxx>

[ Upstream commit f37044fd759b6bc40b6398a978e0b1acdf717372 ]

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")
