In my experience, getting code to work over both IB and iWARP isn't that
hard. The main points are:
- Use the RDMA CM for connection establishment (duh)
- Memory regions used to receive RDMA read responses must have "remote
write" permission (since in the iWARP protocol, RDMA read responses
are basically the same as incoming RDMA write requests)
- Active side of the connection must do the first operation
- Don't use IB-specific features (atomics, immediate data)
