From: Petri Savolainen <petri.savolai...@linaro.org> Added dummy implementation of ones complement calls. Linux generic implementation does not calculate the sum for all incoming packets as it would be wasteful in SW. It's better to wait until application asks it with odp_chksum_ones_comp16(). Later on, the sum could be stored into the packet header, if we found a way to get it from the HW.
