[PATCH v3 07/9] net/mlx5: add testpmd command to query per-queue rate limit

Thank you for the suggestion. But I think keeping both makes sense for different use cases:

- mlx5_tx_burst_mode_get(), it returns a human-readable string describing
  the burst mode. Embedding rate limit info there would mix concerns
  and the information would only be available as unstructured text.

- rte_pmd_mlx5_txq_rate_limit_query() returns some structured data
  (rate_mbps, pp_index, fw_pp_index) that the applications and scripts
  can consume programmatically. The readback via mlx5_devx_cmd_query_sq() is also
  useful for verifying that the firmware actually applied the PP index to the SQ.

Best regards,
  Vincent
