[openib-general] Problem is routing CM REQ

[Sean Hefty]

I agree with what was in your response, however, this is how I interpret your 
answers:

>> Active side QP - DLID
2

>> Passive side QP - DLID
94

>> CM REQ Primary Local Port LID
no answer given

What is carried in the Primary REQ Local Port LID and Primary Remote Port LID 
fields in the REQ?  My claim is that in this example the values are 94 and 93, 
respectively.  The passive side uses these values to configure its QP.  This 
means that the active side requires knowledge of the LIDs that are used on the 
passive side subnet.  If you believe that other values are carried in the REQ, 
what are they, and how are they used?
