[openib-general] Infiniband Subnet Management

[Adit Ranadive]

I am currently using gen2..

Which osm module is present in gen2? Does opensm allow to modify the
VLarb and SLtoVL mappings?

Also, i cant seem to load the modules for ucm, uverbs etc. I am
getting a FATAL:Error inserting ib_ucm (path to ib_ucm.ko): Device or
resource is busy
Any reasons for this?

Regards,
Adit
