Hi Ben, Thanks for your reply.
You told that for invalid queue id, OFPQOFC_BAD_QUEUE error would be returned. But, for invalid flow stat request there is no error type or code. So, you said, that case switch can return stat reply without body. I think, effectively this may lead OpenFlow Controller in confusion. Because, switch may wrongly send stat reply message without body. How does the controller know, which stat reply message is correct? Is the stat reply message(without body) generated from invalid flow stat request or the switch itself behaving incorrectly? So, could you please tell me you opinion on this?
