# DPDK Patch Review

## Summary
This patch refactors driver alias registration by removing the `RTE_PMD_REGISTER_ALIAS` macro and setting `.driver.alias` directly in driver structure definitions. The changes are purely mechanical and improve code clarity. The patch has no correctness bugs or style violations.

## Review Comments

**No errors or warnings found.**

This is a clean refactor that:
- Removes a confusing macro pattern involving static pointer redefinition
- Simplifies alias registration to a straightforward struct member assignment
- Maintains identical runtime behavior
- Makes the code more explicit and easier to understand

The changes are consistent across all affected drivers, and the commit message accurately describes the motivation and approach.
