Jianguo Wu 59a0b022aa ipvlan: Make skb->skb_iif track skb->dev for l3s mode
For l3s mode, skb->dev is set to ipvlan interface in ipvlan_nf_input():
  skb->dev = addr->master->dev
but, skb->skb_iif remain unchanged, this will cause socket lookup failed
if a target socket is bound to a interface, like the following example:

  ip link add ipvlan0 link eth0 type ipvlan mode l3s
  ip addr add dev ipvlan0 192.168.124.111/24
  ip link set ipvlan0 up

  ping -c 1 -I ipvlan0 8.8.8.8
  100% packet loss

This is because there is no match sk in __raw_v4_lookup() as sk->sk_bound_dev_if != dif(skb->skb_iif).
Fix this by make skb->skb_iif track skb->dev in ipvlan_nf_input().

Fixes: c675e06a98 ("ipvlan: decouple l3s mode dependencies from other modes")

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
