> checking
> 
> In the current implementation of single port mode hairpin, the peer queue
> should belong to the same port of the current queue. When the two ports
> hairpin mode is introduced, such checking should be removed to make the
> hairpin queue setup execute successfully since it is not a valid condition
> anymore.
> 
> In the meanwhile, different devices could have different queue configurations.
> The queues number of peer port is unknown to the current device. The
> checking should be removed also.
> 
> If the Tx and Rx port IDs of a hairpin peer are different, only the manual
> binding and explicit Tx flows are supported. Or else, the four combinations of
> modes could be supported. The mode attributes consistency checking will be
> done when connecting the queue with its peer queue.
