Benjamin Berg dfd9aa3e7a wifi: cfg80211: rewrite merging of inherited elements
The cfg80211_gen_new_ie function merges the IEs using inheritance rules.
Rewrite this function to fix issues around inheritance rules. In
particular, vendor elements do not require any special handling, as they
are either all inherited or overridden by the subprofile.
Also, add fragmentation handling as this may be needed in some cases.

This also changes the function to not require making a copy. The new
version could be optimized a bit by explicitly tracking which IEs have
been handled already rather than looking that up again every time.

Note that a small behavioural change is the removal of the SSID special
handling. This should be fine for the MBSSID element, as the SSID must
be included in the subelement.

README

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.
