public/openib-cpc2 branch. "oob" is currently the default.
Unfortunately, it caused quite a few conflicts when I merged with the
trunk, so I created a new temp branch and put all the work there: /tmp-

mpirun --mca btl_openib_cpc_include rdma_cm ...
mpirun --mca btl_openib_cpc_include ibcm ...
You might want to concentrate on testing oob and xoob to ensure that
we didn't cause any regressions. The ibcm and rdma_cm CPCs probably
still have some rough edges (and the IBCM package in OFED itself may
not be 100% -- that's one of the things we're evaluating. It's known
