Remove network drivers' last few uses of theoretically-exploitable network entropy. Only 12 net drivers are affected. Headless boxes should use a more secure source of entropy, such as the userspace daemons rngd, clrngd, egd, audio_entropyd, and/or video_entroyd. I'm also thinking about writing a "Frankenstein" daemon that combines the entropy-collecting algorithms from those daemons into one. Whereas rngd only uses /dev/hw_random, my hypothetical daemon would make a best effort attempt: use /dev/hw_random if it exists, otherwise fallback (or use in addition) the other entropy sources.
