+* **Reorganized the symmetric crypto operation structure.**
+
+ The crypto operation (``rte_crypto_sym_op``) has been reorganized as follows:
+
+ * Removed field ``rte_crypto_sym_op_sess_type``.
+ * Replaced pointer and physical address of IV with offset from the start
+ of the crypto operation.
+ * Moved length and offset of cipher IV to ``rte_crypto_cipher_xform``.
+
+* **Reorganized the crypto operation structure.**
+
+ The crypto operation (``rte_crypto_op``) has been reorganized as follows:
+
+ * Added field ``rte_crypto_op_sess_type``.
+ * Enumerations ``rte_crypto_op_status`` and ``rte_crypto_op_type``
+ have been modified to be uint8_t values.
+ * Removed the field ``opaque_data``.
+ * Pointer to ``rte_crypto_sym_op`` has been replaced with a zero length array.
