Currently input_dev is set in eth_type_trans, ppp_generic and the
mirred action. With your patch we have a couple of drivers more,
but this still leaves lots of non-ethernet drivers that don't set
input_dev. A centralized solutions seems much better to me than
adding this to every single driver. I can't see the problem with
redirected packets, just set skb->input_dev = skb->dev in
netif_receive_skb, this should have exactly the same effect as
setting it in the drivers or the mirred action.
