  There is a standard way for the PPPoE server to notify the RADIUS
server that it has restarted.  The PPPoE server *should* be doing this.

  However... the only reason that RADIUS "knows" the user is already
connected is because you configured it to store user logins (radutmp),
AND you configured it to allow the user on only once.
