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" ?
Thank you
Emmanuel
