  TTUSB_HWSECTIONS:
    the DSP supports filtering in hardware, however, since the "muxstream"
    is a bit braindead (no matching channel masks or no matching filter mask),
    we won't support this - yet. it doesn't event support negative filters,
    so the best way is maybe to keep TTUSB_HWSECTIONS undef'd and just
    parse TS data. USB bandwidth will be a problem when having large
    datastreams, especially for dvb-net, but hey, that's not my problem.

  TTUSB_DISEQC, TTUSB_TONE:
    let the STC do the diseqc/tone stuff. this isn't supported at least with
    my TTUSB, so let it undef'd unless you want to implement another
    frontend. never tested.

  debug:
    define it to > 3 for really hardcore debugging. you probably don't want
    this unless the device doesn't load at all. > 2 for bandwidth statistics.
