Hi Slava,

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
