> In real-life business, one device could be attached and detached dynamically.
> The hairpin configuration of this port to/from all the other ports should be
> enabled and disabled accordingly.
>
> The RTE ethdev lib and PMD should provide this ability to get the peer ports
> list in case that the application doesn't save it. It is recommended that the size
> of the array to save the port IDs is as large as the "RTE_MAX_ETHPORTS" to
> have the maximal capacity.
>
> The order of the peer port IDs may be different from that during hairpin
> queues set in the initialization stage. The peer port ID could be the same as the
> current device port ID when the hairpin peer ports contain itself - the single
> port hairpin.
>
> The application should check the ports' status and decide if the peer port
> should be bound / unbound when starting / stopping the current device.
