Re: [PATCH net/core] dev_forward_skb() should clear skb_iif

While investigating another bug, I found that the code on the incoming path
in __netif_receive_skb will only set skb->skb_iif if it is already 0.  When
dev_forward_skb() is used in the case of interfaces like veth, skb_iif may
already have been set.  Making dev_forward_skb() cause the packet to look
more like a newly received packet would seem to the the correct behaviour
here, as otherwise the wrong incoming interface can be reported for such a
packet.

Same problems as your ipv4 multicast patch, I'm not applying this.

You must learn how to properly submit your changes, otherwise I
guarentee all of your work will hit the bit bucket.
