+Allow Net Devices to contribute to /dev/random
+CONFIG_NET_RANDOM
+ If you say Y here, network device interrupts will contribute to the
+ kernel entropy pool. Normally, block devices and some other devices
+ feed the pool. Some systems, such as those that are headless or diskless,
+ need additional entropy sources. Some people, however, feel that network
+ devices should not contribute to /dev/random because an external attacker
+ could observe incoming packets in an attempt to learn the entropy pool's
+ state. If you say N, no network device will contribute entropy.
+
+ If you believe there is a chance of your network packets being observed
+ and you doubt the security of the entropy pool's one-way hash, do not
+ enable this. If unsure, say N.
