Jan Hoffmann cf6d52f45a ltq-vdsl-vr11-app: perform orderly shutdown on exit
Try to do a clean disconnection via L3 request before the connection is
stopped.

Because this might take up to 6 seconds (the driver does 3 attempts with
a timeout of 2 seconds each), a termination timeout needs to be defined
in the init script.
