   9           Hardware Random Number Generator Core infrastructure.

  11           To compile this driver as a module, choose M here: the
  12           module will be called rng-core.  This provides a device
  13           that's usually called /dev/hw_random, and which exposes one
  14           of possibly several hardware random number generators.
  15
  16           These hardware random number generators do not feed directly
  17           into the kernel's random number generator.  That is usually
  18           handled by the "rngd" daemon.  Documentation/hw_random.txt
  19           has more information.
