Rather than list them all, OMPI will try them all since they are all
compiled. By default, it tries faster networks before TCP. Simply run:
$ mpirun ...
and do not specify the network. It should so the right thing.
I think others have asked for a confirmation of selected network, but
I do not know if that feature exists.
