FIPS 140-2 rng data tester for h/w crypto devices. This driver periodically
monitors the entropy data harvested by crypto drivers to verify it complies with FIPS 140-2. If data fails any test then the driver discards it and commences continuous testing of harvested data until it is deemed ok. Results are collected in a statistics block and, optionally, reported on the console. In normal use the overhead associated with this driver is not noticeable. Note that drivers must (currently) be compiled specially to enable use. Obtained from: original code by Jason L. Wright
