-   *Enable legacy ethernet driver using HAL_ETH_LEGACY_MODULE_ENABLED
-    This will have to be removed once Zephyr driver is migrated to the new
-    Cube HAL ethernet API.
-
    *Wrap define UNUSED with an ifndef
      This will prevent a compiler warning for the case the UNUSED macro
      is already defined elsewhere in the project
