int32_t new_event_threshold
uint16_t dequeue_depth
uint16_t enqueue_depth
uint32_t event_port_cfg

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 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 max_num_events == -1​.

Configure the maximum size of burst dequeues for this event port​. This value cannot exceed the 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​.
