Gracias Jarek.
Paul, (out of curiosity more than anything) what are the circumstances
of the cloned skb - are you going to reinject it back at some point?

I cant think of any good reason why iif shouldnt be copied - thats how
its been from the begining (dammit;->). The reason it hasnt mattered so
far is everything that needs to write the iif never copied (refer to 
Documentation/networking/tc-actions-env-rules.txt). For correctness i
think it should be copied. So no objections;
The better patch would be to just put it in skb_clone and remove it from
tc_act_clone.

cheers,
jamal
