   8 +Allow Net Devices to contribute to /dev/random
   9 +CONFIG_NET_RANDOM
  10 +  If you say Y here, network device interrupts will contribute to the
  11 +  kernel entropy pool. Normally, block devices and some other devices
  12 +  feed the pool. Some systems, such as those that are headless or diskless,
  13 +  need additional entropy sources.  Some people, however, feel that network
  14 +  devices should not contribute to /dev/random because an external attacker
  15 +  could observe incoming packets in an attempt to learn the entropy pool's
  16 +  state.  If you say N, no network device will contribute entropy.
  17 +
  18 +  If you believe there is a chance of your network packets being observed
  19 +  and you doubt the security of the entropy pool's one-way hash, do not
  20 +  enable this.  If unsure, say N.
