* NOTE: It currently lacks support for two ioctl's:

* If the bus has been automatically powered off due to power overload,
* this ioctl call restores the power to the bus. The call requires read/write
* access to the device. This call has no effect if the device is manually
* powered off. Not all DVB adapters support this ioctl.
*
* FE_DISHNETWORK_SEND_LEGACY_CMD is used on av7110, budget, gp8psk and stv0299
* Spec says:
* WARNING: This is a very obscure legacy command, used only at stv0299
* driver. Should not be used on newer drivers.
* It provides a non-standard method for selecting Diseqc voltage on the
* frontend, for Dish Network legacy switches.
* As support for this ioctl were added in 2004, this means that such dishes
* were already legacy in 2004.
*
* So, it doesn't make much sense on implementing support for them.
