I *think* that having rdma_ptr might be useful in its own right,
as a nicer way to get at the ipoib private data, which we need anyway,
dont we?
I am not, however, sure what rdma_ptr should point to?
Some kind of structure including ca, port and pkey?

On a side note, I wander whether ATS can be split into a separate module
so that people that dont need it can avoid loading it.
