# DPDK Patch Review

## Summary
This patch replaces `rte_memcpy()` with structure assignment in the ethdev owner get function. The change is correct and follows DPDK guidelines for control path code.

---

## Errors
None.

---

## Warnings
None.

## Info

### Positive Observations
1. **Appropriate rte_memcpy removal**: This is control path code (port owner retrieval), not fast path. Structure assignment is clearer and preferred here per the guidelines.

2. **Include cleanup**: Removing the now-unused `<rte_memcpy.h>` include is correct.

3. **Correctness preserved**: The spinlock protection remains intact, and the structure assignment semantics are identical to the memcpy for this use case.

### Minor Consideration
The include removal at line 19 (`#include <rte_memcpy.h>`) should be verified to ensure no other code in `rte_ethdev.c` depends on it. A quick check would confirm this is the only usage, making the removal safe.

---

## Conclusion
This is a clean, correct refactoring that improves code clarity in the control path. No issues found.
