[dpdk-dev] [PATCH] net/mlx5: add Rx/Tx burst mode info callbacks

[dpdk-dev] [PATCH] net/mlx5: add Rx/Tx burst mode info callbacks

[Alexander Kozyrev]

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.
