HI list 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? &^עע'6]m^z۫%z^w+^^qyi\&x (f  %y&v͹Ἕ(DL=9PuWivJ+'۳hm5]m]4DyǢ[f  %y&+aHωۼ7p_z((n͢׽8߭4=$( ڶ
