# DPDK Patch Review

## Patch Summary
This patch adds support for 200G link speed reporting in the iavf (Intel AVF) driver for E830 VFs.

---

## Correctness Issues

**None identified.** The patch is straightforward and appears correct. The new case follows the existing pattern for link speed mapping.

---

## Code Style

**No issues found.** The patch:
- Follows the existing switch statement style
- Uses proper indentation (tabs)
- Matches the formatting of surrounding code
- Uses the correct constant (`RTE_ETH_SPEED_NUM_200G`)

---

## API and Documentation Requirements

### **Warning: Missing Release Notes**

The patch adds user-visible functionality (200G link speed support for E830 VFs) but does not update the release notes.

**Suggested fix:**
Add an entry to `doc/guides/rel_notes/release_<current_version>.rst` under the "New Features" section:

```rst
* **Updated iavf driver.**

  * Added support for 200G link speed reporting on E830 VFs.
```

### **Info: Consider Updating Driver Documentation**

If the iavf driver has a dedicated features matrix or documentation listing supported link speeds, consider updating it to include 200G support. Check `doc/guides/nics/intel_vf.rst` or equivalent.

## Summary

The code changes are correct and follow DPDK coding style. The primary issue is the missing release notes entry for this user-visible feature addition.

**Findings by severity:**
- **Errors:** None
- **Warnings:** 1 (missing release notes)
- **Info:** 1 (consider updating driver documentation)
