imq doesn't work on linux-3.14.77

hi,imq team:
I use imq to test QOS,and I was stacked with the issue:
I use the iptable-1.4.10 with imq patch, and kernel-3.14.77 with imq patch;
and set the rule to test QOS, but it doesn't work. it is strange.
it seems the data is goto the imq0 a little, and most data goto the lan directly.
maybe it is releated to netfilter(kernel) or some buffer code?
Any advices?

Hi, can you paste the rules and if you use NAT or no?

hi,
Sorry for not replying for a long time；
we use the htb rule to control, and we just use imq0 to control the download bandwidth.
