-  - Functions ``rte_cryptodev_queue_pair_start()`` and
-    ``rte_cryptodev_queue_pair_stop()`` will be deprecated from 18.05
-    and removed in 18.08, as there are no drivers doing anything useful

   - Some feature flags such as ``RTE_CRYPTODEV_FF_MBUF_SCATTER_GATHER`` are ambiguous,
     so some will be replaced by more explicit flags.
   - Function ``rte_cryptodev_get_header_session_size()`` will be deprecated
