> bursts
>
> If an application issues rte_event_enqueue_new_burst() or
> rte_event_enqueue_forward_burst() call with a burst of events longer than the
> configured max enqueue burst size, DSW allocates credits not only for events
> actually enqueued, but for the complete burst. If this process is repeated,
> enough credits will have leaked to cause the event device to backpressure
> (i.e.
> disallow) any new enqueue operations.
>
> In addition, the port-level enqueue xstats will log the wrong number of events
> enqueued for oversized enqueues.
>
> This patch makes DSW gracefully handle oversized enqueue bursts.
