Sounds like a good thing to do.

Just a minor point/question:

I forget why IB_SEND_MAD_GRH_VALID is needed. Isn't the grh setup
properly in the AH which is supplied with the send WR ? However, the
notion of IB_SEND_MAD is needed to determine whether the timeout_ms
parameter is to be honored or not.
