[dpdk-dev] [PATCH] net/mlx5: improve logging of MPRQ selection

[Alexander Kozyrev <akozyrev@mellanox.com>]

MPRQ is silently turned off in case there is not enough
Rx queues configured. Improve the logging to show a
warning in this case to notify a user about the Rx burst
function selected.

Fixes: 7d6bf6b866b8 ("net/mlx5: add Multi-Packet Rx support")
