Now vsock only support send/receive small packet, it can't achieve high performance. As previous discussed with Jason Wang, I revisit the idea of vhost-net about mergeable rx buffer and implement the mergeable rx buffer in vhost-vsock, it can allow big packet to be scattered in into different buffers and improve performance obviously. I write a tool to test the vhost-vsock performance, mainly

When vhost support VIRTIO_VSOCK_F_MRG_RXBUF feature, it will merge big packet into rx vq.
