Perhaps we should pursue changing this in the IBTA spec. Being able to post to the SQ while in RTR makes handling of the Comm Est/RTU race with the CQ callback much easier to handle. It would be better if the IB spec permitted posting to the SQ in RTR but indicated the SQ would not be processed until the QP moved to RTS. I believe the present Mellanox silicon/firmware implements such behavior.
