When a completion queue is full, the associated queue pairs are not put into the error state. According to the IBTA specification, this is a violation. Quote from IBTA spec: C9-218: A Requester Class F error occurs when the CQ is inaccessible or full and an attempt is made to complete a WQE. The Affected QP shall be moved to the error state and affiliated asynchronous errors generated as described in 11.6.3.1 Affiliated Asynchronous Events on page 678. The current WQE and any subsequent WQEs are left in an unknown state. C11-37: The CI shall generate a CQ Error when a CQ overrun is detected. This condition will result in an Affiliated Asynchronous Error for any associated Work Queues when they attempt to use that CQ. Completions can no longer be added to the CQ. It is not guaranteed that completions present in the CQ at the time the error occurred can be retrieved. Possible causes include a CQ overrun or a CQ protection error. Put the qp in error state when cq is full. Implement a state called full to continue to put other associated QPs in error state.
