# DPDK Patch Review

## ERRORS

None.

## WARNINGS

None.

## INFO

The patch correctly changes `mac_idx` from a global symbol to file-static scope.
This is good practice to avoid namespace pollution and potential static linking conflicts.

The `const` qualifier is already present, which is appropriate for this compile-time constant array.

Review-Result: CLEAN
