This series adds support for CQ notifications through the verbs api (ibv_req_notify_cq/ibv_get_cq_event). In order to achieve that, a new event queue (EQ) object is introduced, which is in charge of reporting completion events to the driver. In addition, a new CQ doorbell is introduced that is mmapped to the userspace provider in order to arm the CQ when requested by the user.
