> Subject: [PATCH v2] net/mlx5: fix info about Rx descriptors for MPRQ
> 
> The number of descriptors configured is returned to a user via the rxq_info_get
> API. This number is incorrect for MPRQ.
> For SPRQ this number matches the number of mbufs allocated.
> For MPRQ we have fewer external MPRQ buffers that can hold multiple
> packets in strides of this big buffer. Take that into account and return the
> number of MPRQ buffers multiplied by the number of strides in this case.
