If the driver triggers a reset by writing zero into the status register then reset the underlying device if supported. A device reset also requires resetting various aspects of the queue. In order to be able to do a subsequent reactivate it is required to reclaim certain resources (interrupt and queue EventFDs.) If a device reset is requested by the driver but the underlying device does not support it then generate an error as the driver would not be able to configure it anyway.
