+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.
