The ibtool version of this switches the starting LID with the connected switch in this case.. Having that general functionality means you can easially write a traceroute routine with this common code. Note, doing tricks like this with the DR path screws up the localPortNum value, so if you ever read Port/NodeInfo using a path that has been manipulated like this it needs a fixup step. Also, there is a bug, you can't DLID route to the local HCA and then use that as a source of a DR path, even though intuitively that should work.
