What I meant is, you could have only changed the function documentation.

 @return
   0 on success with rte_errno always set, negative errno otherwise.

letting the function documentation saying rte_errno is only modified in
case of error whereas it is not is a bug or in the documentation or in
the code, but as a function must respect its documentation, it would
have raised a bug in the code itself.
