Questions on RTS->SQD

Questions on RTS->SQD

[Guay Wei Lin]

Hi, 

As for an experiment for my research to try out the SQD state, I've reused
the perftest code (send_bw.c) to modify the QP state from RTS->SQD, and
query_qp to make sure the QP is in the SQD state. The codes were added
before ibv_post_send function. (to make sure no outstanding WR in the SQ).
When the ibv_modify_qp is executed to modify QP from RTS->SQD, it returns a
0 without any error code, but when the ibv_query_qp to query on the
QP_state, the QP is still in RTS state. I'm using the mlx4 HCAs. Any
ideas/suggestions why this will happen or I miss out something?

Thanks,
