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.

Thanks.
