Bug description:
  [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.

  upstream commit which fixing this problem:
  http://cgit.freedesktop.org/NetworkManager/NetworkManager/commit/?id=eb460b70dad82d366d35fa5703c0e79a1389e4d1
