There doesn't seem to be enough documentation anywhere even to decide
whether such an enterprise is possible. CSA appears to be proprietary,
so, Intel being Intel, you probably need a license to hook up to that
port with an infiniband adapter of your own creation. Anyone have a
clue otherwise? I feel almost silly asking, because every bit of
evidence I've seen indicates that Intel is trying to create a
competitive advantage for its own network silicon by giving it unique
access to the MCH.
