Guess you don't mean IB router when you say router in your description.
I also have no theories without more information:
Is the sender a normal node ? Is normal node mean standard OpenIB
without changes ? How was the SMI changed ? On which nodes ? Only the
intermediate one ?
Aside from the initial path being [0][1][1], what are the hop count and
hop pointer ? What are DrDLID and DrSLID as well as the LIDs in the LRH
of the SMP ?
