From: Michael Qiu <qiud...@chinac.com> Currently, OVS only support DPDK single segment mbuf, it could lead problems, like a large non-DPDK source packet transmit to dpdk port.
Also, OVS doesn't copy enough info in mbuf when do packet copy. At the same time, vlan and tunnelling packet's DPDK offloads, for example TSO, needs multi-segment mbuf's support. This patchset solved all above issues. -- v1 --> v2 rebase code to newest upstream. fix some typo in commit log.
