STABLE14-mask-loopback-address-allow-loopback-interfaces-to-be-advertised-20041110

some software network adapters use instances of lo but are real network adapters
. allow them to be advertised. the modified functions are called only in the pro
cess of collecting a list to advertise.

at the same time, make sure we mask 127.0.0.1.
i wonder if that's a mistake.
