So what is one to do if a few applications want to read from /dev/random but you have no excellent source of entropy on the system? Wait forever? I think ethernet interrupts are better than nothing, and I really doubt that someone would be able to predict what the entropy generated would be in practice. If you have that good access to the physical network, then probably have physical access to the system itself, in which case it is all irrelevant.
