Notify queue of pending events.
This method is called by VirtIODeviceBase::onNotify() to notify the device model of pending data in a virtqueue. The default implementation of this method iterates over the available descriptor chains and calls onNotifyDescriptor() for every new incoming chain.
Device models should normally overload one of onNotify() and onNotifyDescriptor().
Reimplemented from gem5::VirtQueue.
