Could it be useful to provide the patch? I already submitted a patch providing segmentation offload a few months ago: http://dpdk.org/ml/archives/dev/2014-May/002537.html A part of this series has been reworked by Bruce and is now integrated in head. I think rebasing the rest of the series should not be too difficult since Bruce's work is based on this series. Unfortunately, I won't have time to do the rebase by myself in the coming weeks, but feel free to do it if you need this feature. Regards, Olivier
