Public bug reported:

After fixing IPv6 address assignment (#1469346), IPv6 works fine until
sleep. On wake up ubuntu fails to renew its IPv6 lease:

Jan 13 10:47:47 ubuntu dhclient: PRC: Renewing lease on wlp3s0.
Jan 13 10:47:47 ubuntu dhclient: PRC: Rebinding lease on wlp3s0.
Jan 13 10:47:47 ubuntu dhclient: XMT: Rebind on wlp3s0, interval 9890ms.
Jan 13 10:47:47 ubuntu NetworkManager[796]: <info>  (wlp3s0): DHCPv6 state changed bound -> unknown
Jan 13 10:47:47 ubuntu dhclient: PRC: Address 2a02:xxxx:xxxx:xxxx::b44 depreferred.
Jan 13 10:47:47 ubuntu NetworkManager[796]: <info>  (wlp3s0): DHCPv6 state changed unknown -> expire
Jan 13 10:47:47 ubuntu NetworkManager[796]: <info>  (wlp3s0): canceled DHCP transaction, DHCP client pid 1170
Jan 13 10:47:47 ubuntu NetworkManager[796]: <info>  (wlp3s0): DHCPv6 state changed expire -> done

I'm not sure that it's solely NetworkManager issue (dhclient could also
be affected).
