Should we look at sending in a structure with some of this information?  Right now, I think we have 4 parameters (device, flags, in_mad, out_mad).  And we want to add in QP number, port number, and LID.  Am I missing something?

Port number seems like it could have its own parameter.  For the source LID, would it be possible to use a flag for locally generated MADs?  (Not suggesting this over using the source LID, just trying to see what other options there are.)

Also, I didn't quite follow the reasoning for the QP number parameter.
