> 
> This patch removes the limitation of 8 queue pairs by
> dynamically allocating vring metadata once we know the
> maximum number of queue pairs supported by the backend.
> 
> This is especially useful for Vhost-vDPA with physical
> devices, where the maximum queues supported may be much
> more than 8 pairs.
