max_virtqueue_pairs is enabled with VIRTIO_NET_F_RSS

[mstsirkin]

the spec says:

\item Identify and initialize the receive and
transmission virtqueues, up to N of each kind. If
VIRTIO_NET_F_MQ feature bit is negotiated,
N=\field{max_virtqueue_pairs}, otherwise identify N=1.

\item If the VIRTIO_NET_F_CTRL_VQ feature bit is negotiated,
identify the control virtqueue.

\item Fill the receive queues with buffers: see \ref{sec:Device Types / Network Device / Device Operation / Setting Up Receive Buffers}.

\item Even with VIRTIO_NET_F_MQ, only receiveq1, transmitq1 and
controlq are used by default. The driver would send the
VIRTIO_NET_CTRL_MQ_VQ_PAIRS_SET command specifying the
number of the transmit and receive queues to use.

but this is incomplete: max_virtqueue_pairs is also used in the same way
with VIRTIO_NET_F_RSS.

Going through old issues... what is the current status of this?
