# DPDK Patch Review

## Summary
This patch promotes three telemetry API functions from experimental to stable status. The changes are straightforward: removing `__rte_experimental` attributes from headers and updating export macros from `RTE_EXPORT_EXPERIMENTAL_SYMBOL` to `RTE_EXPORT_SYMBOL`.

## Findings

### Errors
None.

### Warnings
None.

### Info

**Release notes format** (Info):
The release notes entry is placed in the "API Changes" section, which is appropriate for API promotion. The formatting follows DPDK conventions with a bullet list of the promoted functions. This is acceptable documentation of the stability change.

**Export macro updates** (Info):
The patch correctly updates the export macros in the `.c` files:
- `rte_telemetry_register_cmd_arg`: changed from `RTE_EXPORT_EXPERIMENTAL_SYMBOL(name, 24.11)` to `RTE_EXPORT_SYMBOL(name)`
- `rte_tel_data_add_array_uint_hex`: changed from `RTE_EXPORT_EXPERIMENTAL_SYMBOL(name, 23.03)` to `RTE_EXPORT_SYMBOL(name)`
- `rte_tel_data_add_dict_uint_hex`: changed from `RTE_EXPORT_EXPERIMENTAL_SYMBOL(name, 23.03)` to `RTE_EXPORT_SYMBOL(name)`

This follows the correct pattern for promoting experimental symbols to stable.

**Header attribute removal** (Info):
The `__rte_experimental` attributes are correctly removed from all three function declarations in `rte_telemetry.h`. The functions remain properly documented with their existing Doxygen comments.

## Conclusion
The patch is clean and follows DPDK guidelines for API promotion. The changes are minimal, focused, and correctly implemented. No issues requiring fixes were identified.
