Hi Andreas,

i haven?t tested the patch for now, but i think it should work, because i
have the last days played around a bit with this values (inspired by the
Metzler?s driver witch use always buf[1] = 2 for software section
filtering).

Software filtering works fine with buf[1] = 2 (i think the driver works a
little bit more stable with this for me), but for hw_sections = 1 the value
must be > 2, with an value of 2 the card lost pakets (i get disortions).

Greetings
Andreas
