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.
