Then there was an agreement to rework mbuf in 1.8 version to implement TSO on top of it. Then it was suggested to rebase his work: http://dpdk.org/ml/archives/dev/2014-September/006151.html How does your patchset match with Olivier's work on TSO and ixgbe driver? I would like to ensure the API works fine for all TSO-capable driver, this would be a good start. Thanks -- Thomas
