# Review of DPDK Patch: mailmap email address update

## Summary

This patch updates a mailmap entry to redirect historical contributions from an old email address to a new one. The patch is **correct and follows DPDK conventions** for mailmap updates.

---

## Detailed Review

### PASS: Correctness

No code changes are present in this patch. The mailmap file is a metadata mapping and does not affect compilation, runtime behavior, or API.

### PASS: C Coding Style

Not applicable - this patch only modifies `.mailmap`, which is not C code.

### PASS: API and Documentation Requirements

Not applicable - mailmap changes do not affect API or require documentation updates.

### PASS: Mailmap Format

The mailmap entry follows the correct format for redirecting an old email to a new canonical address:

```
New Name <new at email> <old at email>
```

This will cause Git to map all commits from `14pwcse1224 at uetpeshawar.edu.pk` to `khadem.systems at gmail.com` for attribution purposes, which is the stated intent in the commit message.

---

## Findings

**No issues found.**

This is a straightforward administrative change that correctly updates the contributor's contact information in the mailmap. The format is correct, the commit message clearly states the purpose, and no code or documentation is affected.
