Make EntropyMixer mix in output of Hardware RNG into Linux RNG. On devices with Hardware RNG (HW RNG), this makes EntropyMixer periodically (every three hours) read 512 bytes from HW RNG and mix them into the Linux RNG. This is done without increasing Linux RNG's entropy estimates to avoid having to trust the quality of the HW RNG. This approach cannot reduce the quality of the Linux RNG output, but may increase it.
