> Subject: [PATCH] examples/ntb: remove redundant logic for dev close
> 
> During EAL cleanup stage, all bus devices are cleaned up properly.
> Based on this, there is no need to do extra device close process, which may
> call the dev ops '*dev->dev_ops->dev_close' twice.
> 
> If this dev ops for ntb was called twice, the interrupt handle for EAL will be
> disabled twice and will lead to error for the seconde time. Like this: "EAL:
> Error disabling MSI-X interrupts for fd xx"
> 
> Thus, this patch just remove the redundant logic for device close.
> Ports will be closed at rte_eal_cleanup() in the main loop.
