getifaddrs for en1 gives 3 different addresses
After using getifaddrs and I am looking at en1 wireless interfaces. When I
printed them out I have seen 3 different interfaces for en1.
en1 Unknown family (18)
en1 fe80::219:e3ff:fe04:ac2d
en1 10.185.199.30
I think only the last one has a valid IP address. Why the other two existed?
