Support outer L3 and inner L3 + L4 Tx checksum offload for GTP-U packets
that contain extension header on FVL.
Support outer L3 + L4 and inner L3 + L4 Rx and Tx checksum offload for
GTP-U packets that contain extension header on CVL.

To support Tx side offload on GTP tunneling packet, driver should
set correct tunneling parameters of 'L4TUNT'.

To enable Tx side offload on GTP-U packets that contain extension header,
testpmd should set 'info->l2_len' correctly, this value should contain UDP
header length, GTP-U header length and GTP-U extension header length.
