As the 802.11 spec evolves, we need to parse more and more
elements. This is causing the struct to grow, and we can no
longer get away with putting it on the stack.
Change the API to always dynamically allocate and return an
allocated pointer that must be kfree()d later.
As an alternative, I contemplated a scheme whereby we'd say
in the code which elements we needed, e.g.
DECLARE_ELEMENT_PARSER(elems,
SUPPORTED_CHANNELS,
CHANNEL_SWITCH,
EXT(KEY_DELIVERY));
ieee802_11_parse_elems(..., &elems, ...);
and while I think this is possible and will save us a lot
since most individual places only care about a small subset
of the elements, it ended up being a bit more work since a
lot of places do the parsing and then pass the struct to
other functions, sometimes with multiple levels.

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.
