Subject: [RFC] remove skb->dev NULL assignation
I was trying to figure out why in the tcp_v4_rcv/tcp_v6_rcv function,
the skb->dev field is set to NULL. There is certainly a good reason,
but I was not able to find it.
Is it possible to remove this ?

It is illegal to reference a device outside of the netif_receive_skb()
code path without taking a reference to it.
Since we are queueing it to a socket, we have to NULL out the skb->dev
since thee packets lifetime is being expanded outside of that allowed
window.
Got it. Thank you very much.
