> Networking under KVM works best if we allocate a per-vCPU rx and tx
> queue in a virtual NIC. This requires a per-vCPU queue on the host side.
> Modern physical NICs have multiqueue support for large number of queues.
> To scale vNIC to run multiple queues parallel to maximum number of vCPU's
> we need to increase number of queues support in tuntap.
