 * cryptodev: the ``uint8_t *data`` member of ``key`` structure in the xforms
   structure (``rte_crypto_cipher_xform``, ``rte_crypto_auth_xform``, and

+* cryptodev: support for using IV with all sizes is added, J0 still can

+  ``rte_crypto_aead_xform`` is set to zero. When IV length is greater or equal
+  to one it means it represents IV, when is set to zero it means J0 is used
+  directly, in this case 16 bytes of J0 need to be passed.
