[arch-general] NetworkManager attribute but doesn't use ipv6

[Yamakaky]

Hi

I have a problem with nm : it seems to get an ipv6 address from dhcp, 
but it doesn't use it.

		ip addr

inet 192.168.0.5/24 brd 192.168.0.255 scope global wifi
    valid_lft forever preferred_lft forever
inet6 *:*:*:*:*:*:8f3e:7de1/64 scope global noprefixroute dynamic
    valid_lft 86334sec preferred_lft 86334sec

		ip -6 route

*:*:*:*::/64 dev wifi  proto kernel  metric 303  mtu 1480
fe80::/64 dev wifi  proto kernel  metric 256

(I replaced my ipv6 by * for privacy)

Web sites like http://whatismyipv6.com/ say that I don't have an ipv6.

I searched on the web, but nothing concluant. Any idea ?
