The object to enable/disable FIPS mode on the device.
FIPS 140-2 is a set of security requirements for cryptographic
modules and it details the U.S. Government requirements for
cryptographic modules.
A module will comprise both hardware and software, eg a
datacenter switching or routing module. The module is said to
be in FIPS enabled mode when a request is recieved to enable the
FIPS mode and a set of self-tests are successfully run in
response to the request. If the self-tests fail, then an
appropriate error is returned.
