  Name resolution stops working after resume from suspend

Status in network-manager package in Ubuntu:

Bug description:
  After upgrading to Yakkety, when my Ubuntu GNOME laptop resumes from
  suspend DNS resolution stops working.

  After resuming, systemd-resolved is running and libnss-resolve is
  installed, but /etc/resolv.conf contains as the the only
  name server. The dnsmasq-base package is installed since it is pulled
  in by both network-manager and lxc1, and both NM and libvirt have
  spawned instances of dnsmasq:

  >  1155 pts/2    S+     0:00 grep dnsmasq
  >  2724 ?        S      0:00 dnsmasq -u lxc-dnsmasq --strict-order 
--bind-interfaces --pid-file=/run/lxc/ --listen-address 
--dhcp-range, --dhcp-lease-max=253 --dhcp-no-override 
--except-interface=lo --interface=lxcbr0 
--dhcp-leasefile=/var/lib/misc/dnsmasq.lxcbr0.leases --dhcp-authoritative
  >  2992 ?        S      0:00 /usr/sbin/dnsmasq 
--conf-file=/var/lib/libvirt/dnsmasq/default.conf --leasefile-ro 
  >  2993 ?        S      0:00 /usr/sbin/dnsmasq 
--conf-file=/var/lib/libvirt/dnsmasq/default.conf --leasefile-ro 
  > 22879 ?        S      0:00 /usr/sbin/dnsmasq --no-resolv 
--keep-in-foreground --no-hosts --bind-interfaces

--cache-size=0 --conf-file=/dev/null --proxy-dnssec 

  Let me know if you need any extra info.
