There is no "anything > else" here -> there is no *anything* > -- 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. http://marc.info/?l=openssl-dev&m=121095151003011&w=2
