Shirley, you are right.
I just wanted share our experience with you.

All the tests we made on our IPoIB driver, so our NAPI implementation 
isn't relevant here.
Unfortunately, we didn't plan to work on the IPoIB performance in the 
nearest future, so I can't
implement NAPI on the OpenIB driver right now.

I think it would be very interesting to compare the NAPI performance 
against the work queue.
Please let me know if you are planning to do it yourself.
