  36 Description
  37 ===========
  38
  39 .. warning::
  40    This is a very obscure legacy command, used only at stv0299
  41    driver. Should not be used on newer drivers.
  42
  43 It provides a non-standard method for selecting Diseqc voltage on the
  44 frontend, for Dish Network legacy switches.
  45
  46 As support for this ioctl were added in 2004, this means that such
  47 dishes were already legacy in 2004.
