> When testpmd quit with mlx5 avail_thresh enabled, a rte timer handler
> delays to reconfigure rx queue to re-arm this event. However at the same
> time, testpmd is destroying rx queues.
> It's never a valid use case for mlx5 avail_thresh. Before testpmd quit,
> user should disable avail_thresh configuration to not handle the events.
> This is documented in mlx5 driver guide.
> 
> To avoid the crash in such use case, check port status, if it is not
> RTE_PORT_STARTED, don't process the avail_thresh event.
