+Subject: networkd: link - fix stopping v4 dhcpclient when the carrier is lost
+
+The check for a running v4 dhcpclient was using DHCP_SUPPORT_V6 flag
+instead of DHCP_SUPPORT_V4.
+
+As a result, when the carrier was lost systemd was not cleaning up the
+relevant addresses and routes. If the carrier was regained in another
+environment, with a different subnet and gateway, the system would end
+up with multiple addresses and default gateways and thus a broken
+network configuration. This scenario can be easily reproduced with wifi
+links.
+
+Bug-Debian: http://bugs.debian.org/779571
+Forwarded: No, fixed upstream in 217 as side effect of commit ba179154.
