Xiong Zhang 4cbcc26f5c Virtio-net: Add multi queues in multi threads ... In order to support 2 vq pairs for virtio-net, this patch create 2 sockets in one tap interface, 2 vq pairs(rx/tx) and 2 threads in device model, So one vq pair has one thread and one socket in tap corresponding. On my SkyLake desktop with crosvm and ubuntu 18.04 guest: If run one iperf server on host and one iperf client in guest, 2 vq pairs has the same netwrok bandwidth as 1 vq pair, the bandwidth is 5.99Gbits/sec If run two iperf server on host and two iperf client in guest, In 1 vq pair mode, two iperf cliens bandwidth are 3.19Gbits/sec and 3.18Gbits/sec. In 2 vq pairs mode, two iperf clients bandwidth are 4.87Gbits/sec and 4.86Gbits/sec. So 2 vq pairs improve net bandwidth 52.7% compared with 1 vq pair in this case.
