Title:
  virtio-net ignores the absence of the VIRTIO_NET_F_CTRL_VQ feature bit

Status in QEMU:
  Expired

Bug description:
  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.
