hi , Werner :)
i do the following modification to the net/sched/sch_ingress.c
ingress_enqueue() function , i simply add the following lines
after the line 169: skb->tc_index = TC_H_MIN(res.classid);
if (skb->tc_index > 0xf || skb->tc_index == 0) {
switch (skb->protocol) {
case __constant_htons(ETH_P_IP):
ipv4_change_dsfield(skb->nh.iph,
0x3,skb->tc_index);
break;
case __constant_htons(ETH_P_IPV6):
ipv6_change_dsfield(skb->nh.ipv6h,
0x3,skb->tc_index);
break;
default:
break;
};
};
it works currently, but wonder whether there will be
any negative influence or not. would you please give
some comment on this ?
again , thanks for your precious time.
another thing, i noticed that since the dsmark dequeue
function does not support mpls protocol, so when a mpls
packet arrives, it complains "unsupported protocol".
Although the tcindex value is still there, it just cannot
use it . i think this is where the problem lies in.
folke.
