Previously, it's implemented in the v3 of the patchset, which you are referring to, but abandoned in the v4. v3: http://thread.gmane.org/gmane.comp.networking.dpdk.devel/27512 v8: http://thread.gmane.org/gmane.comp.networking.dpdk.devel/32743 It may be because that there's no consumers (L4 stack) for this feature. And if you want that, you could make that as a reference. Thanks, Jianfeng > > Thanks, > Nissim
