Jose Ignacio Tornos Martinez e31daf5fbc wifi: rtw89: 8922a: set random mac if efuse contains zeroes
[ Upstream commit 41be33d3ef ]

I have some rtl8922ae devices with no permanent mac stored in efuse.

It could be properly saved and/or configured from user tools like
NetworkManager, but it would be desirable to be able to initialize it
somehow to get the device working by default.

So, in the same way as with other devices, if the mac address read from
efuse contains zeros, a random mac address is assigned to at least allow
operation, and the user is warned about this in case any action needs to
be considered.

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 reStructuredText 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.
