Does KVM virtio-net support multiple interrupt queues?

Issue

• Does KVM virtio-net support multiple interrupt queues?
• How can I enable multiple TX queues in virtio TX path. This allows a single guest to transmit multiple flows of network data using multiple CPUs simultaneously via multiple TX queues in virtio-net/vhost-net/macvtap.
• Does the virtio-net driver support RPS (Receive Packet Steering) and XPS (Transmit Packet Steering)?
