It is a different thing, during OFA16 conference we were **strongly advised** to move from old read/write interface in RDMA stack to something else. The agreement was that a couple of weeks after the conference, Liran will organize open web meeting to discuss what we want from this interface. It is important to make it open, so all participants will be able to express their willingness. Intel as usual decided to do it in their way and the result is presented on this mailing list.
