In case of Geneve packet we check HW offload support of SWP in mlx5e_tunnel_features_check() and set features accordingly, this should be reflected in skb offload requested by the kernel and we should add the Software Parser offsets only if requested. Otherwise, in case HW doesn't support SWP for Geneve, data path will mistakenly try to offload Geneve SKBs with skb->encapsulation set, regardless of whether offload was requested or not on this specific SKB.
