+Enable event vectorization
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The event crypto adapter can aggregate outcoming crypto operations based on
+provided response information of ``rte_event_crypto_metadata::response_info``
+and generate a ``rte_event`` containing ``rte_event_vector`` whose event type
+is ``RTE_EVENT_TYPE_CRYPTODEV_VECTOR``.
+To enable vectorization application should set
+RTE_EVENT_CRYPTO_ADAPTER_EVENT_VECTOR in
+``rte_event_crypto_adapter_queue_conf::flag`` and provide vector
+configuration(size, mempool, etc.) with respect of
+``rte_event_crypto_adapter_vector_limits``, which could be obtained by calling
+``rte_event_crypto_adapter_vector_limits_get()``.
+
+The RTE_EVENT_CRYPTO_ADAPTER_CAP_EVENT_VECTOR capability indicates whether
+PMD supports this feature.
+
