Since commit 9d5804662c ("ath10k: retrieve MAC address from system
firmware if provided"), we support pulling our MAC address from system
firmware. Along with this, we should admit that it's possible for system
firmware to be screwed up as well, omitting the MAC address there.
Provide a fallback, such that we choose a randomly-generated MAC
address, with the local assignment bit set.
This is not a preferred mode of operation and really should only serve
the purpose of keeping the system chugging along while someone figures
out what's wrong with the system. Grepping through other wireless
drivers shows very similar fallback logic though, so why not?

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
