Thanks for all the replies, let me add some background around the
motivation for this change.
On some systems we have seen large delays in boot time, due to
blocking on a call to getrandom() before the entropy pool has been
initialized. On these systems the usual sources of entropy are not
suffici

It is now possible for drivers to easily specify a hwrng quality, however
most do not currently do this, and in cases where they do, it may be
desirable to override the driver-specified value with a user-specified
one. This patch adds a parameter to set or override the hwrng quality.
