# DPDK Patch Review

## Summary
This patch promotes three telemetry functions from experimental to stable API. The changes are minimal and appropriate for an API promotion.

## Info

### Documentation and Process
1. **Release notes update is appropriate**: The patch correctly documents the API promotion in the current release notes file (`release_26_11.rst`) with the list of promoted functions.

2. **Export symbol changes are correct**: The patch properly changes from `RTE_EXPORT_EXPERIMENTAL_SYMBOL(name, version)` to `RTE_EXPORT_SYMBOL(name)` for all three functions:
   - `rte_telemetry_register_cmd_arg` (24.11 - stable)
   - `rte_tel_data_add_array_uint_hex` (23.03 - stable)
   - `rte_tel_data_add_dict_uint_hex` (23.03 - stable)

3. **Header file cleanup is correct**: Removal of `__rte_experimental` attributes from the three function declarations in `rte_telemetry.h` is appropriate.

### Style and Correctness
The patch follows DPDK conventions:
- Does not manually edit `version.map` files (correct - these are auto-generated)
- Updates export macros in `.c` files only
- Maintains consistent formatting
- No code logic changes, only API stability annotations

### Justification
The commit message provides reasonable justification:
- Hexadecimal helpers stable since v23.03 (3+ years in this future scenario)
- `rte_telemetry_register_cmd_arg` stable since v24.11 (~2 years)

This timeframe is sufficient for API stabilization.

## Overall Assessment
**APPROVED** - This is a clean API promotion patch with appropriate documentation, correct symbol export changes, and no code correctness issues. The patch is ready for integration.
