Field Documentation

   int32_t new_event_threshold
       A backpressure threshold for new event enqueues on this port. Use for closed system event dev where event
       capacity is limited, and cannot exceed the capacity of the event dev.

       Configuring ports with different thresholds can make higher priority traffic less likely to be
       backpressured. For example, a port used to inject NIC Rx packets into the event dev can have a lower
       threshold so as not to overwhelm the device, while ports used for worker pools can have a higher
       threshold. This value cannot exceed the rte_event_dev_config::nb_events_limit value which was previously
       supplied to rte_event_dev_configure().

       This should be set to '-1' for open system, i.e when rte_event_dev_info::max_num_events == -1.

   uint16_t dequeue_depth
       Configure the maximum size of burst dequeues for this event port. This value cannot exceed the
       rte_event_dev_config::nb_event_port_dequeue_depth value which was previously supplied to
       rte_event_dev_configure().

       Ignored when device does not support the RTE_EVENT_DEV_CAP_BURST_MODE capability.

   uint16_t enqueue_depth
       Configure the maximum size of burst enqueues to this event port. This value cannot exceed the
       rte_event_dev_config::nb_event_port_enqueue_depth value which was previously supplied to
       rte_event_dev_configure().

       Ignored when device does not support the RTE_EVENT_DEV_CAP_BURST_MODE capability.
