I think I'm asking you about the non RDMACM stuff in openmpi, ibcm, xoob, etc. I can't tell at glance if any of them will be safe to run on RDMAoE as-is.. At least it looks like there are some basic problems, like oob doesn't exchange a GID, or setup the AH to use a GRH. Basically, if setting transport_type == IB for RDMAoE breaks existing stuff then it probably isn't a good strategy.
