Public bug reported:
When negotiating virtio-net feature bits, the device ignores the absence
of the VIRTIO_NET_F_CTRL_VQ bit in driver feature bits and provides
three virtqueues, including the control virtqueue, even though the
driver is expecting only the receive and transmit virtqueues. Looking
into the source code, it appears it always assumes the presence of the
control virtqueue, violating thus the VIRTIO version 1.0 specification.
