---

## Findings

### No Issues Found

After thorough review against the AGENTS.md guidelines, this patch does not contain any correctness bugs, style violations, or guideline violations.

**Verification performed:**
-  No code changes -- only build configuration
-  Alphabetical ordering maintained in the examples list
-  Proper meson syntax (single-quoted string in list)
-  References existing commit that added the example
-  Appropriately tagged for stable backport
-  No forbidden tokens or patterns
-  No API changes requiring documentation updates
-  No release notes needed (build-only fix)

The patch correctly integrates the previously added `ptp_tap_relay_sw` example into the build system, maintaining alphabetical order as required by DPDK meson build conventions.
