I haven't seen these patches but this seems poor to me. I think any app that isn't using rdmacm will need patching and support for RDMAOE (certainly all mine will). libibverbs shouldn't overload the existing transport_type checks for something that is not 100% compatible with IB. Is the same true for openmpi? If you try to run it as is on a RDMAOE interface will it work? If not I think that alone should kill this idea..
