That wouldn't happen when you were using a secure PRNG to select the interrupts to get data from, or ? You just have to make sure that the PRNG initial state is not seeded from the network or anything else the attacker could guess.
Well, the question I thought that was being asked was why wasn't the interrupts from NIC's feeding in entropy by default into the /dev/random pool.
I'm not sure what you mean about using a secure PRNG to select the interrupts to get data from; there's a bootstrapping issue here, and even if you do use a PRNG to select whether or not a particular entropy is sampled, that decision only contributes one bit of entropy into the pool.....
