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

135 You may want to disable the network support on embedded devices. If

170 By default, a media driver auto-selects all possible i2c
171 devices that are used by any of the supported devices.
172
173 This is generally the right thing to do, except when there
174 are strict constraints with regards to the kernel size,
175 like on embedded systems.
176
177 Use this option with care, as deselecting ancillary drivers which
178 are, in fact, necessary will result in the lack of the needed
179 functionality for your device (it may not tune or may not have
180 the need demodulers).
181
182 If unsure say Y.
