What I had in mind was something like:

./opensm --dev /devinfiniband/umad0 

to work on port 1 only

and 

./opensm --dev /dev/infiniband/umad*

to work on all ports of all devices.

/dev/infiniband/umad* could be a default (maybe set at configure time
or by varibale in makefile), but otherwise I really think *forcing* a specific
udev scheme is a problem, since this makes udev scheme part of abi,
but not checkable by abiversion.
