When the MAC address read from the efuse data is invalid, warn the user and use a random MAC address instead. On a device I am currently using (Anbernic RG-ARC) with a rtw8821cs the efuse appears to be incompletely/improperly programmed. The MAC address reads as ff:ff:ff:ff:ff:ff. When networkmanager attempts to initiate a connection (and I haven't hard-coded a MAC address or set it to random) it fails to establish a connection.

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.
