>Description:
If getifaddrs() is called we will see for example the following addresses:

fe80:0001:0000:0000:0a00:27ff:fe69:3ee5
0000:0000:0000:0000:0000:0000:0000:0001
fe80:0003:0000:0000:0000:0000:0000:0001

The first and last addresses are wrong, the 4. byte don't contain 0 as expected.
The value 1 or 3 correspond to the scope id as reported by ifconfig
>How-To-Repeat:
use a little program using getifaddrs and print out the IPv6 addresses.
>Fix:
