Remove RND_FLAG_NO_ESTIMATE and comment claiming we can't estimate (which

means "count", in this context) the entropy we're adding because we poll the
device periodically.  Sure, we poll it periodically, but it's a hardware
RNG -- the data returned should be random no matter when we read the
register!
