...queue is full, the transmitting packet is queued up and it will be sent in the next iteration. This causes the same packet to be delivered multiple times to monitoring devices. This patch fixes this issue, postponing the packet delivery to monitoring devices, only when it is properly queued in the virqueue.

RSS (Receive-side scaling) defines hash calculation rules and decision on receive virtqueue according to the calculated hash, provided mask to apply and provided indirection table containing indices of receive virqueues. The driver sends the control command to enable multiqueue and provide parameters for receive steering.
