This had some issue with VLANs where the VLAN ID was set by the driver even when offload support was enabled. Fix: Upstream (v5.11-rc3) commit 378d3783412e38dc3a2b9d524f551c0008ea314a "net/mlx5e: Fix SWP offsets when vlan inserted by driver" was backported (dropping some code because it did not yet exist in 5.8) and verified to address the problem. Testcase: Enable geneve tunnel offload support on a mlx5(e) card over VLAN.
