[PATCH] net/i40e: support GTP in tunnel parameters parsing

[Yijun Geng]

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. During TX checksum offloading,
the incorrect L3 header offset was used when calculating the inner IP
checksum,  resulting in modifying the length field of the GTP header.
