Why overwrite?
You could've done it above:

	struct mlx5_flow_dv_encap_decap_resource res = {
		.reformat_type =
			MLX5DV_FLOW_ACTION_PACKET_REFORMAT_TYPE_L2_TO_L2_TUNNEL,
  		.ft_type = transfer ? MLX5DV_FLOW_TABLE_TYPE_FDB :
				      MLX5DV_FLOW_TABLE_TYPE_NIC_TX,
	};

Same for the rest.

This res has nothing to do with encap/decap but it is
mlx5_flow_dv_modify_hdr_resource.
