That's funny
It does look to disturb some kernel developper that ethernet may be sniffed
to feed a RNG
even that could be very hard to reach any effective result in the case of a
machine splitting
different network segments.

In the same time, it does not disturb openssl developpers to include non
initialised
memory that may or may not be predictable to feed a RNG.
