Eg that it is a SEND ONLY QP and only works for UD. Verbs UD QP can handle receive of ingress packets sent with BTH.DestQPN = ibv_qp->qp_num. This is applicable also in this case. Also, future implementation might include RC source qpn use case. This can be accomplished by setting the HCA's QPN to be the same as the 'source qpn' value, and returning that to the user. We prefer not to limit the API definition in the man page.
