TCF_EM_META_LVALUE will be unused in this case.

ok - i get it. So the rvalue is basically just the data that needs to be
compared against. rvalue confused me a little. If you had called it
meta_data i would have got it right away. But now that you explain it,
makes sense. 

I am not sure iam following yet:

So in the case of indev, you would need to 
- get indev ifindex from skb
- get indev name from skb
- compare the two??

Actually it may be a little overkill to have those two as separate
entities with their own headers etc, no? Why not just store it in the
same fashion you transported it from/to user space? 

I will start looking at the code
