+An application can use ``rte_cryptodev_asym_session_pool_create()`` to create a mempool
+with a specified number of elements. The element size will allow for the session header,

+The max private session size is chosen based on available crypto devices,
+the biggest private session size is used. This means any of those devices can be used,
+and the mempool element will have available space for its private session data.
Once the session mempools have been created, ``rte_cryptodev_asym_session_create()``

-The session then must be initialized using ``rte_cryptodev_asym_session_init()``

* ethdev: Old public macros and enumeration constants without ``RTE_ETH_`` prefix,
which are kept for backward compatibility, are marked as deprecated.
+* cryptodev: The asymmetric session handling was modified to use a single
+ mempool object. An API ``rte_cryptodev_asym_session_pool_create`` was added
+ to create a mempool with element size big enough to hold the generic asymmetric
+ session header and max size for a device private session data.
+ The API ``rte_cryptodev_asym_session_init`` was removed as the initialization
