+----------------------------------------------------------------------
+
+It is not necessary to check the type of the queue on post_send and
+post_recv since the QP type that cannot be supported will be rejected
+when it is created.
+
+Check for srq in post_recv has also been removed, because the RQ of
+QP bound to srq is empty and will return immediate error in post_recv.
+
+Besides, remove the unused parameter ctx.

+In cases such as using XRC and SRQ where RQs are not created, the recv_cq
