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
