Subject: dev: introduce dev_get_iflink()

The goal of this patch is to prepare the removal of the iflink field. It
introduces a new ndo function, which will be implemented by virtual interfaces.

There is no functional change into this patch. All readers of iflink field
now call dev_get_iflink().

Subject: netfilter: Make nf_hookfn use nf_hook_state.

Pass the nf_hook_state all the way down into the hook
functions themselves.

From 7026b1ddb6b8d4e6ee33dc2bd06c0ca8746fa7ab Mon Sep 17 00:00:00 2001
From: David Miller <davem@davemloft.net>
Date: Sun, 5 Apr 2015 22:19:04 -0400
Subject: netfilter: Pass socket pointer down through okfn().

On the output paths in particular, we have to sometimes deal with two
socket contexts.  First, and usually skb->sk, is the local socket that
generated the frame.

And second, is potentially the socket used to control a tunneling
socket, such as one the encapsulates using UDP.

We do not want to disassociate skb->sk when encapsulating in order
to fix this, because that would break socket memory accounting.

The most extreme case where this can cause huge problems is an
AF_PACKET socket transmitting over a vxlan device.  We hit code
paths doing checks that assume they are dealing with an ipv4
socket, but are actually operating upon the AF_PACKET one.
