Apple M1 Mac minis (2020) with 10GE NICs do not have MAC address in the card, but instead need to obtain MAC addresses from the device tree. In this case the hardware will report an invalid MAC. Currently atlantic driver does not query the DT for MAC address and will randomly assign a MAC if the NIC doesn't have a permanent MAC burnt in. This patch causes the driver to perfer a valid MAC address from OF (if present) over HW self-reported MAC and only fall back to a random MAC address when neither of them is valid.

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.
