net/mlx5: add Rx/Tx burst mode info
Get a burst mode information for Rx/Tx queues in mlx5. Provide callback functions to show this information in a "show rxq info" and "show txq info" output. Signed-off-by: Alexander Kozyrev <akozyrev@mellanox.com> Acked-by: Viacheslav Ovsiienko <viacheslavo@mellanox.com>
