+The mydlink tools will set up two URLs in `/tmp/db/device.cf`:
+```
+      "FirmwareDaemonURL": "http://mp-eu-fwd.auto.mydlink.com:80/fw-upgrade",
+      "SecuredFirmwareDaemonURL": "https://mp-eu-fwd.auto.mydlink.com:443/fw-upgrade",
+```
+
+Calling either one of these with a model parameter will return a
+download URL for the latest firmware version.  Examples:
+
+```
