Eventq is a special virtqueue. The driver
(e.g. SPDK virtio) enqueues some fixed
amount of write-only requests. The host
device completes them only when it has
something to tell us - like a device
hotremove. After we receive the response,
containing full event details, we schedule
proper action and re-enqueue the event to
be used later by the host as another event.
