I think that the optimization works even with RMPP.  Assuming that most receives are for a one MAD, it allocates a single structure, rather than two that then need to be chained together.  For RMPP, you can still have more recv_buf's chained together.  It's just that the first recv_buf is included with the mad_recv_wc, rather than being linked off of it.
