Zide Chen aef6e53ed9 virtio-net: reduce number of virtual interrupts to the guest ... It's quite costly to inject virtual interrupt to the guest, especially in INTx case. To reduce the number of interrupts, in process_rx(), we don't have to inject interrupt on every frame, but wait until process_rx() finishes processing all frames. On eve, iperf3 gets ~15% improvement, "iperf3 -R" gets ~30% improvement.
