NAME
     rte_event_port_conf

SYNOPSIS
     #include <rte_eventdev.h>

   Data Fields
     int32_t new_event_threshold
     uint16_t dequeue_depth
     uint16_t enqueue_depth
     uint32_t event_port_cfg

Detailed Description
     Event port configuration structure

     Definition at line 1178 of file rte_eventdev.h.

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 traf-
     fic 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 over-
     whelm the device, while ports used for  worker  pools  can  have  a  higher
     threshold.    This    value    cannot    exceed	the   rte_event_dev_con-
     fig::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 capa-
     bility.

   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 capa-
     bility.
