I'm curious as to what mentions osmtest. Are you talking about OpenIB
(gen2) or gen1 ?

The documentation is in userspace/management. There is a README and a
user manual and release notes under that in osm/doc.

Not sure what you mean by test an infiniband setup.

Is it back to back HCAs ?

Were these manually configured IP addresses ?

Are you just looking to run IPoIB ?

To bring up an IB subnet, you need an SM to bring the ports to active.
Then you can start to talk some ULPs.

There is info on bringing up IPoIB in linux-kernel/docs. There are
ipoib.txt and ipoib_faq.txt.

There is also a wiki which was started:
https://openib.org/tiki/tiki-index.php?page=MellanoxHcaFirmware

Hope this is enough to get you rolling...
