Currently, all Infiniband users must create a process for polling their completion queues (or rely on a regular hook such as netdev_poll() in ipoib.c). Move instead to a model whereby the Infiniband core maintains a single process calling ib_poll_eq(), and polling the event queue triggers polls of the applicable completion queues. (At present, the Infiniband core simply polls all of the device's completion queues.) Polling a completion queue will now implicitly refill all attached receive work queues; this is analogous to the way that netdev_poll() implicitly refills the RX ring. Infiniband users no longer need to create a process just to poll their completion queues and refill their receive rings.
