[Impact]

 * dhcpv6 sets an incorrect netmask on ipv6 networks, leading to
probable communication failures in certain networks

[Test Case]

 * You need an ipv6 network using dhcpv6 statefull configuration with
prefix which is not equal to /64

[Regression Potential]

 * None, this patch has been accepted upstream and is available since
quantal

network-manager in ubuntu precise use incorrect /64 prefix from dhcpv6
client which cause that internet connection not working on some ipv6
networks. this problem was fixed in upstream network-manager version
0.9.6 which is already available in ubuntu quantal and newer - but not
in ubuntu precise. because this is critical problem (non working
network/internet) new version of network manager (e.g 0.9.6) or at least
patch which fixing this problem should be included in ubuntu precise
which is LTS.
