# DPDK Patch Review

## Summary
This patch updates the `.mailmap` file to change the ordering of entries for contributor "Zhang Tengfei". The patch moves the entry from the "T" section to the "Z" section to maintain alphabetical order by the primary (canonical) name.

## Review Findings

### Info

**Alphabetical ordering of .mailmap entries**

The `.mailmap` file maintains alphabetical order by the canonical (left-hand side) name. The patch moves the entry for "Zhang Tengfei" from line 1683 (under "Tengfei Zhang") to line 1983 (under "Zhang Tengfei"), which correctly reflects that "Zhang Tengfei" is now the primary name.

This is the correct approach - `.mailmap` entries should be sorted by the canonical name (the name that appears on the left side of the mapping), not by alternate spellings.

**No issues found.**

The patch is a simple administrative update to `.mailmap` with no code, API, or documentation impact. It correctly maintains alphabetical ordering and follows the standard mailmap format.
