v3] app/testpmd: perform SW IP checksum for GRO/GSO
packets
The GRO/GSO library doesn't re-calculate checksums for merged/fragmented
packets. If users want the packets to have correct IP checksums, they should
select HW IP checksum calculation for the port which the packets are
transmitted to

The GRO/GSO library doesn't re-calculate checksums for
merged/fragmented packets. If users want the packets to
have correct IP checksums, they should select HW IP
checksum calculation for the port which the packets are
transmitted to. But if the port doesn't support HW IP
checksum, users may perfor
