Re: regarding the changes to kernel entropy gathering

[nia <nia%NetBSD.org@localhost>]

I have updated the rndctl(8) documentation so it reflects the current
model in the kernel and is no longer misleading.

It could still use some extra work (e.g. -l could print number of
samples collected).

The kernel already mixes in hardclock jitter, among other things,
to the entropy pool, but it doesn't increase the entropy estimate.
Nothing does except hardware RNGs and direct entropy fed from the
host machine, and there have been strong objections to re-introducing
any kind of estimator that is based purely on runtime statistical
gathering rather than models of hardware.

"Potential entropy gathering schemes" have been discussed to 
death. Please stay on-topic.
