When parsing a frame containing a multi-BSSID element, we
need to know both the transmitted and non-transmitted BSSID
so we can parse it correctly.
Unfortunately, in quite a number of cases, we got this wrong
and were passing the wrong BSSID or useless information:
* the mgmt->bssid from a frame is only the transmitted
BSSID if the frame is a beacon
* passing just one of the parameters as non-NULL isn't
useful and ignored
In those case where we need to parse for a specific BSS we
always have a BSS structure pointer, representing the BSS
we need, whether transmitted or not. Thus, pass that pointer
to the parsing function instead of the two BSSIDs.
Also fix two bugs:
* we need to re-parse all the elements for the other BSS
when iterating the non-transmitted BSSes in scan
* we need to parse for the correct BSS when setting up
the channel data in client code

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.
