I was just looking at your QoS Script. Did you ever notice that no
packets will be put into gred dp3 ?
I was using a similar script based on AF examples on the web and
apparently in the gred qdisc now when you declare 3 dps they are
numbered 0,1,2 and not 1,2,3.
This line in gred_enqueue in sch_gred.c will prevent packets that you
have given a tcindex of 113,123,133,143 of being put in the right dp.
They will get put into the default dp.
if ( ((skb->tc_index&0xf) > (t->DPs -1)) || !(q=t->tab[skb-
>tc_index&0xf])) {
This isnt a bug in the code either as I found out.
You could take the -1 out of this line or else use gred DP0 , DP1, DP2
and change your tcindex classifiers to 110,111,112
