As a prerequisite of per-netns RTNL, we must fetch netns before
looking up dev or moving it to another netns.
rtnl_link_get_net_capable() is called in rtnl_newlink_create() and
do_setlink(), but both of them need to be moved to the RTNL-independent
region, which will be rtnl_newlink().
Let's call rtnl_link_get_net_capable() in rtnl_newlink() and pass the
netns down to where needed.
Note that the latter two have not passed the nets to do_setlink() yet
but will do so after the remaining rtnl_link_get_net_capable() is moved
to rtnl_setlink() later.
While at it, dest_net is renamed to tgt_net in rtnl_newlink_create() to
align with rtnl_{del,set}link().

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 reStructuredText 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.
