356 * The request for this originates from the VF IWARP driver through

358 * A vector could have an AEQ and CEQ attached to it although
359 * there is a single AEQ per VF IWARP instance in which case
360 * most vectors will have an INVALID_IDX for aeq and valid idx for ceq.
361 * There will never be a case where there will be multiple CEQs attached
362 * to a single vector.
363 * PF configures interrupt mapping and returns status.
