    I agree with you. However, I have to let it could be reproduced
    for confirming it.

    Besides, the behavior is different for PCIe and USB device. There
    is no action of DMA for USB device. It is done by the USB host
    controller. And, the USB host controller wouldn't allow the device
    sends a data which is more than the size of the buffer.

    Best Regards,
    Hayes
