net/mlx5e: Fail attempt to offload e-switch TC encap flows with vlan on underlay
Currently we don't support nor fail attempts to offload encap flows routed to vlan device on the underlay network. We wrongly consider a vlan underlay device to be on the same e-switch b/c the switchdev ID is retrieved recursively. Add explicit check for that and fail such attempts. Also align to a more strict check for the ingress and the underlay devices to practically be on the same eswitch. Fixes: ce99f6b97fcd ('net/mlx5e: Support SRIOV TC encapsulation offloads for IPv6 tunnels') Fixes: 3e621b19b0bb ('net/mlx5e: Support TC encapsulation offloads with upper devices') Signed-off-by: Eli Britstein <elibr@mellanox.com> Reviewed-by: Roi Dayan <roid@mellanox.com> Signed-off-by: Saeed Mahameed <saeedm@mellanox.com>
