Hello:
In function init_net_IPv6, I set "fe80::219:dbff:fea9:f3d5"
for my eth0 ipv6 address. But _show_all_interfaces says my ip is
"fe80:1::219:dbff:fea9:f3d5". I don't know why it adds a "1" in it.
The prefix I set is "fe80:0:0:0" .
ipv6: fe80::219:dbff:fea9:f3d5, in6mask64: ff ff ff ff ff ff ff ff
0xa0b53204 - eth0 - 192.168.1.239
0xa0b53220 - eth0 - fe80:1::200:ff:fe6c:18f0
0xa0b5323c - eth0 - fe80:1::219:dbff:fea9:f3d5
0xa0b53274 - lo0 - ::1
0xa0b53290 can_send: 1
