[openib-general] Query regarding posting unsignaled send descriptors

To post an unsignaled send, you must create the QP with sq_sig_all = 0.
Then make sure that IBV_SEND_SIGNALED is _not_ set in the work request
you post.

I'm pretty sure this works because people have reported problems with
buggy applications that never posted any signaled sends.
