Either use netif_rx()/ for complete packets that should go through the whole stack again or nf_reinject() from your hook.

Is it really possible to call netif_rx from netfilter hook? I try to call netif_rx(skb) from PRE_ROUTING hook (returning NF_STOLEN) and kernel immediately crashes, even if I did nothing with skb at all. Why it happens this way?
