	  This option enables DVB experimental memory-mapped API, which

	  This option enables DVB Network Support which is a part of the DVB
	  standard. It is used, for example, by automatic firmware updates used
	  on Set-Top-Boxes. It can also be used to access the Internet via the
	  DVB card, if the network provider supports it.

	  You may want to disable the network support on embedded devices. If
	  unsure say Y.

	  By default, a media driver auto-selects all possible ancillary
	  devices such as tuners, sensors, video encoders/decoders and
	  frontends, that are used by any of the supported devices.

	  This is generally the right thing to do, except when there
	  are strict constraints with regards to the kernel size,
	  like on embedded systems.

	  Use this option with care, as deselecting ancillary drivers which
	  are, in fact, necessary will result in the lack of the needed
	  functionality for your device (it may not tune or may not have
	  the needed demodulators).

	  If unsure say Y.
