[dpdk-dev] [PATCH] net/mlx5: fix minimum size of Multi-Packet Rx queue

> The size of Rx queue is determined by dividing the number of descriptors by
> the number of strides. As device can't support single slot queue, if the
> number of descriptors is same as the number of strides, MPRQ shouldn't be
> enabled. Otherwise, this will cause HW fault. For example, if rxd is set to
> 512 with testpmd on ConnectX-4 Lx, PMD can't receive more than 512 packets
> because the minimum number of strides for ConnectX-4 Lx is 512. Users have
> to configure larger number of descriptors in this case.
