+Tx event vectorization
+~~~~~~~~~~~~~~~~~~~~~~
+
+The event device, ethernet device pairs which support the capability
+``RTE_EVENT_ETH_TX_ADAPTER_CAP_EVENT_VECTOR`` can process event vector of mbufs.
+Additionally, application can provide a hint to the Tx adapter that all the
+mbufs are destined to the same ethernet port and queue by setting the bit
+``rte_event_vector::attr_valid`` and filling `rte_event_vector::port`` and
+``rte_event_vector::queue``.
+If ``rte_event_vector::attr_valid`` is not set then the Tx adapter should peek
+into each mbuf and transmit them to the requested ethernet port and queue pair.
