  42   TTUSB_HWSECTIONS:
  43     the DSP supports filtering in hardware, however, since the "muxstream"
  44     is a bit braindead (no matching channel masks or no matching filter mask),
  45     we won't support this - yet. it doesn't event support negative filters,
  46     so the best way is maybe to keep TTUSB_HWSECTIONS undef'd and just
  47     parse TS data. USB bandwidth will be a problem when having large
  48     datastreams, especially for dvb-net, but hey, that's not my problem.
  49
  50   TTUSB_DISEQC, TTUSB_TONE:
  51     let the STC do the diseqc/tone stuff. this isn't supported at least with
  52     my TTUSB, so let it undef'd unless you want to implement another
  53     frontend. never tested.
  54
  55   debug:
  56     define it to > 3 for really hardcore debugging. you probably don't want
  57     this unless the device doesn't load at all. > 2 for bandwidth statistics.
