436 own drivers. It registers itself as a standard hardware random number
437 generator, major 10, minor 183, and the canonical device name is
439 The way to make use of this is to install the rng-tools package
440 (check your distro, or download from
441 http://sourceforge.net/projects/gkernel/). rngd periodically reads
442 /dev/hwrng and injects the entropy into /dev/random.
