a lower-numbered one.
Notably, there is no mention of queue index assignments changing based on
negotiated features in either of these sections. Hence a reader can only
assume that the queue index assignments are fixed (i.e. stats_vq will
always be vq index 4 if F_STATS_VQ is negotiated, regardless of any other
feature bits).
Now consider a scenario where VIRTIO_BALLOON_F_STATS_VQ and
VIRTIO_BALLOON_F_PAGE_REPORTING are negotiated but
VIRTIO_BALLOON_F_FREE_PAGE_HINT is not (perhaps the device supports all of
the defined features but the driver only wants to use repo...
