The series introduces the ibv_modify_cq verb to enable CQ moderation, it can be extended in the future for other options by using the attr_mask field. By using the ibv_modify_cq verb a user can moderate completion events by specifying the number of completions that cause an event and the timeout in micro seconds to cause the event even if the number of completions was not reached. The series includes below: Patch #1: Exposes the related moderation capabilities via ibv_query_device_ex. Patch #2 Introduces the ibv_modify_cq verb to enable the moderation.
