Subject: [PATCH] net/i40e: add gtp tunnel type in i40e_parse_tunneling_params

i40e I40E_TX_OFFLOAD_MASK indicates that all tunnel types are supported,
but gtp type is not considered in i40e_parse_tunneling_params(),
tunneling parameter: L4TUNLEN is not set. Inner IP checksum calculation
used the wrong L3 header offset, resulting in modifying the length
field of the GTP header.
