Maybe even that's not needed. Couldn't skb->queue_mapping give the correct NAPI instance in multiqueue nics? The NAPI instance could be made easily available from skb->dev. In any case an index is much better than a new pointer.
We do not keep skb->dev information once a packet leaves the rcu protected region. Once packet is queued to tcp input queues, skb->dev is NULL.
