Guest receive mergeable rx buffer, it can merge scatter rx buffer into a big buffer and then copy to user space. In addition, it also use iovec to replace buf in struct virtio_vsock_pkt, keep tx and rx consistency. The only difference is now tx still uses a segment of continuous physical memory to implement.
