Multiple queue support
----------------------
Multiple queue is treated as a protocol extension, hence the slave has
to implement protocol features first. The multiple queues feature is
supported only when the protocol feature ``VHOST_USER_PROTOCOL_F_MQ``
(bit 0) is set.
Multiple queue support allows the slave to advertise the maximum number of
queues. This is treated as a protocol extension, hence the slave has to
implement protocol features first. The multiple queues feature is supported
only when the protocol feature ``VHOST_USER_PROTOCOL_F_MQ`` (bit 0) is set.
The max number of queue pairs the slave supports can be queried with
message ``VHOST_USER_GET_QUEUE_NUM``. Master should stop when the
number of requested queues is bigger than that.
The max number of queues the slave supports can be queried with message
``VHOST_USER_GET_QUEUE_NUM``. Master should stop when the number of requested
queues is bigger than that.
As all queues share one connection, the master uses a unique index for each
queue in the sent message to identify a specified queue. One queue pair
is enabled initially. More queues are enabled dynamically, by sending
message ``VHOST_USER_SET_VRING_ENABLE``.

The master enables queues by sending message ``VHOST_USER_SET_VRING_ENABLE``.
vhost-user-net has historically automatically enabled the first queue pair.
