This part is actually just the old method we used to get transport type, I'm
not sure about the usage of this 'transport' so reserve the old way for it :-P
Actually I can't locate the place using this stuff in core layer, thus I guess it
may be used by user layer or the protocol, as long as these layer using the old
logical, we better don't touch anything ;-)
