Can you point me the spec page talking about zero-length rdma-write and
send ?

If I use zero-length rdma write, does it generate something on wire to
let me detect broken connection, and there is no effect on remote buffer
?

If I use zero-length send, do I get the same thing? How about if I don't
have receive posted on remote side ?
