Sure, in that case a different packet is dropped, once again you
can trace it with kfree_skb() if you want. What's the problem?

It's ok, but we can make it better. Yunsheng Lin may have explained why?

Why it is better to trace dropped packets both in enqueue and in kfree_skb()?
I fail to see it. You are just asking for duplications. If you do not see it by
yourself, it means you don't understand or need it at all. ;)

Thanks.
