    net/i40e: fix outer UDP checksum offload for X710

    According to the X710 datasheet (and confirmed on the field..), X710
    devices do not support outer checksum offload.

    """
    8.4.4.2 Transmit L3 and L4 Integrity Offload

    Tunneling UDP headers and GRE header are not offloaded while the
    X710/XXV710/XL710 leaves their checksum field as is.
    If a checksum is required, software should provide it as well as the in=
ner
    checksum value(s) that are required for the outer checksum.
    """

    Fix Tx offload capabilities according to the hardware.

    X722 may support such offload by setting I40E_TXD_CTX_QW0_L4T_CS_MASK.
