So? There are substantial semantic differences for *all* non-rdmacm applications. Even common ones like OpenMPI.

Nonsense. RDMAoE is no such thing, it is utterly incompatible with the IB management model. It is some new protocol that is only about 90% compatible with IB. Apps using rdmacm shouldn't care one way or the other, apps that don't *need* a new transport type.
