In the 17.11 version ,lib gso was introduced.
I just want to check it's performance.
The output segments from the rte_gso_segments() were multi-segments mbuf, at the same time, rte_gso_segments() don't calculate the checksum for the out put tcp seg, so , the application have to calculate the csum by itself.
But the current rte_udptcp_csum() interface can't calculate the checksum of multi-segment mbuf.
Who know how to do it?
