Just so everyone is clear here, the test to run only on Infiniband in the
above cases is done by checking the transport_type for Infiniband:
if (IBV_TRANSPORT_IB != btl->device->ib_dev->transport_type) {
The code protected by this doesn't work on RDMAoE so RDMAoE must not
set transport_type to IBV_TRANSPORT_IB.
