In fact, this patch set is v2 of [1], but I consider that the vhost checksum offload capability is also supported in this version, and send a new patch set out.
The patch set add the negotiation between us-vhost and virtio-net for vhost TX offload(checksum and TSO), and add the TX offload support in the libs and change vhost sample and csum application to test these changes.
