The adapter configuration parameters defined in the
``struct rte_event_crypto_adapter_params`` can be configured
and retrieved using ``rte_event_crypto_adapter_set_params``
and ``rte_event_eth_rx_adapter_get_params`` respectively.

+Set/Get adapter configuration parameters
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The configuration parameters of adapter can be set/read using
+``rte_event_crypto_adapter_set_params()`` and
+``rte_event_crypto_adapter_get_params()`` respectively. The parameters that
+can be set/read are defined in ``struct rte_event_crypto_adapter_params``.
+
+``rte_event_crypto_adapter_create()`` configures the adapter with
+default value for maximum packets processed per request to 128.
+``rte_event_crypto_adapter_set_params()`` function allows to reconfigure
+maximum number of packets processed by adapter per service request. This is
+alternative to configuring the maximum packets processed per request by adapter
+by using ``rte_event_crypto_adapter_create_ext()`` with parameter
+``rte_event_crypto_adapter_conf::max_nb``.
+
+``rte_event_crypto_adapter_get_parmas()`` function retrieves the configuration
+parameters that are defined in ``struct rte_event_crypto_adapter_params``.
