The WWAN core not only multiplex the netdev configuration data, but process it too, and needs some space to store its private data associated with the netdev. Add a structure to keep common WWAN core data. The structure will be stored inside the netdev private data before WWAN driver private data and have a field to make it easier to access the driver data. Also add a helper function that simplifies drivers access to their data. At the moment we use the common WWAN private data to store the WWAN data link (channel) id at the time the link is created, and report it back to user using the .fill_info() RTNL callback. This should help the user to be aware which network interface is bound to which WWAN device data channel.

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.
