    is that humor? :)

    it can certainly generate a large amount of entropy if you let it.

    but the general mechanism for grabbing entropy from char/net devices is
    measuring values from their interrupt timings. this is done via a flag
    value in request_irq.

    loopback has no interrupts thus no request_irq
