[openib-general] Cray XD1 and OpenSM.. (ignoreing certain guids?)

[Troy Benjegerdes]

In the interest of plugging absolutely everything I have with infiniband
ports together and seeing what falls over, I connected a Cray XD1 to a
small (2 machine) infiniband network running OpenSM.

Ideally, I'd like to find out what sort of minimal emulation code needs
to be running on the XD1 nodes to answer standards compliant SM
requests. Failing that, Is there a way we can tell OpenSM to ignore parts 
of the IB network? I am seeing a lot of stuff in the osm.log like this:

(port 16 is on the internal mellanox chip in the XD1)
