    Because you ignored my explanations.

    Read the Kdoc help text in the patch. It explains it.

    No. Read this:
    I will explain it once again: It is _just_ to select a default policy
    of which RNG is initialized by default. The type does say _nothing_
    about the entropy quality or something else. It _just_ judges about
    which RNG is preferred for default initialization.
    External RNG boards are preferred over internal onboard stuff; onboard
    is preferred over bad RNGs like bcm43xx; bcm43xx is preferred over
    devices that are not RNGs by definition but could be used as such (sensors).
