DO NOT ENABLE THIS OPTION UNLESS YOU KNOW WHAT YOU'RE DOING.
This option enables the Request API for the Media controller and V4L2
interfaces. It is currently needed by a few stateless codec drivers.
There is currently no intention to provide API or ABI stability for
this new API as of yet.

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.

help
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.
