194	  By default, a media driver auto-selects all possible ancillary

196	  frontends, that are used by any of the supported devices.

198	  This is generally the right thing to do, except when there
199	  are strict constraints with regards to the kernel size,
200	  like on embedded systems.
201
202	  Use this option with care, as deselecting ancillary drivers which
203	  are, in fact, necessary will result in the lack of the needed
