Taehee Yoo 0bad834ca7 ipvlan: advertise link netns via netlink
Assign rtnl_link_ops->get_link_net() callback so that IFLA_LINK_NETNSID is
added to rtnetlink messages.

Test commands:
    ip netns add nst
    ip link add dummy0 type dummy
    ip link add ipvlan0 link dummy0 type ipvlan
    ip link set ipvlan0 netns nst
    ip netns exec nst ip link show ipvlan0

Result:
    ---Before---
    6: ipvlan0@if5: <BROADCAST,MULTICAST> ...
        link/ether 82:3a:78🆎60:50 brd ff:ff:ff:ff:ff:ff

    ---After---
    12: ipvlan0@if11: <BROADCAST,MULTICAST> ...
        link/ether 42:b1:ad:57:4e:27 brd ff:ff:ff:ff:ff:ff link-netnsid 0
                                                           ~~~~~~~~~~~~~~

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.
