+Rx event vectorization
+~~~~~~~~~~~~~~~~~~~~~~
+
+The event devices, ethernet device pairs which support the capability
+``RTE_EVENT_ETH_RX_ADAPTER_CAP_EVENT_VECTOR`` can aggregate packets based on
+flow characteristics and generate a ``rte_event`` containing ``rte_event_vector``
+whose event type is either ``RTE_EVENT_TYPE_ETHDEV_VECTOR`` or
+``RTE_EVENT_TYPE_ETH_RX_ADAPTER_VECTOR``.
+The aggregation size and timeout are configurable at a queue level and the
+maximum, minimum vector sizes and timeouts vary based on the device capability
+and can be queried using ``rte_event_eth_rx_adapter_vector_limits_get``.
+The Rx adapter additionally might include useful data such as ethernet device
+port and queue identifier in the ``rte_event_vector::port`` and
+``rte_event_vector::queue`` and mark ``rte_event_vector::attr_valid`` as true.
+
+A loop processing ``rte_event_vector`` containing mbufs is shown below.
