Hi Leo (may I ?) and the others, I am reading your howto. Very clear too. But there is one point I don''t understand. I thought that DS said : "one PHB for one DSCP" an we have a table for it I mean if DSCP=0x30 this is AF12 So why should tc_index do that thing ( skb->tc_index & p.mask ) >> p.shift BTW Are mask=0xfc shift=2 mandatory ? if it is only to make another maping it seems a little bit strange. Is it easier to map 12 with a class rather than 0x30 ??? I don''t think (for a computer) Well why isn''t it : "one DSCP --> one class" ?
