TCP Segment Offload for DPDK vRouter

Vrouter does Tx and Rx TCP segmentation offload in the kernel mode currently. It largely leverages kernel APIs for achieving this. However, wrt DPDK, the library lacks segmentation support/API’s and hence DPDK based vrouter cannot do the offloads. For achieving line rate performance of TCP based workloads on 10G NIC’s, we need DPDK based vrouter to support offloads.
