New API replacing previous one
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
If a new API proposed functionally replaces an existing one, when the new API
becomes non-experimental then the old one is marked with ``__rte_deprecated``.
Deprecated APIs are removed completely just after the next LTS.
Reminder that old API should follow deprecation process to be removed.
