net: Make skb->skb_iif always track skb->dev
Make it follow device decapsulation, from things such as VLAN and bonding. The stuff that actually cares about pre-demuxed device pointers, is handled by the "orig_dev" variable in __netif_receive_skb(). And the only consumer of that is the po->origdev feature of AF_PACKET sockets. Signed-off-by: David S. Miller <davem@davemloft.net>
