IMHO, xfrm_neigh_lookup is not used often. If used,
it should be from a place before skb->dst xforms are popped in
xfrm_output_one, i.e. somewhere before the output processing.
I see that dst_neigh_lookup*() is used mostly in xmit handlers
of tunnel devices, I assume, after xfrm_output_one().
Not sure for br_nf_pre_routing_finish_bridge().
I'm trying to fix this code but we have the
same problem as in xfrm_confirm_neigh: to find address
of last tunnel. Should we use the same loop?
