Actually, I think I'm wrong. On my system, /dev/infiniband_mad is the
same device as /dev/infiniband/umad1, and /dev/infiniband_verbs is the
same device as /dev/infiniband/uverbs0.

Should the device nodes /dev/infiniband_mad and /dev/infiniband_verbs
exist at all? Are they artifacts of the way the classes work, or a
setup problem on my system? Do other people have these nodes?

Unless I've gotten it wrong (again), I believe /dev/infiniband/ucm (as
it exists) is an appropriate device name for the userlevel cm.

Sorry for the confusion.
