ibv_req_notify_cq - request completion notification on a completion queue (CQ)
int ibv_req_notify_cq(struct ibv_cq *cq, int solicited_only);
ibv_req_notify_cq() requests a completion notification on the completion
queue (CQ) cq.
Upon the addition of a new CQ entry (CQE) to cq, a
completion event will be added to the completion channel associated with the
CQ. If the argument solicited_only is zero, a completion event is
generated for any new CQE. If solicited_only is non-zero, an event is
only generated for a new CQE with that is considered "solicited."
A CQE is solicited if it is a receive completion for a message with the
Solicited Event header bit set, or if the status is not successful. All
other successful receive completions, or any successful send completion is
ibv_req_notify_cq() returns 0 on success, or the value of errno on
failure (which indicates the failure reason).
The request for notification is "one shot." Only one completion event
will be generated for each call to ibv_req_notify_cq().
