From b68581778cd0051a3fb9a2b614dee7eccb5127ff Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Mon, 23 Jul 2012 16:27:54 -0700 Subject: [PATCH] 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.
