Okay, I re-read the fastreg patch. So it seems what you want to do is to
allocate the fastreg_mr once, and remap it several times. Correct?
Then this fits the current model quite well, except that we need
to splice the whole thing into the send cq handling (so that we
get told when the MR was mapped).

Am I supposed to use the send WQ for mapping the MR, or could one
use a separate WQ - so that we avoid stalling the MR mapping behind
a large queue of send WRs?

Anyway, I looked at your code and tried to fold it back into the IB
code. It seems except for the RDMA code there's not a huge difference
there. I'll post a patch based on your work later today
