Due to the inclusion of nvmem handling into the mac-address getter function of_get_mac_address() by commitd01f449c00("of_net: add NVMEM support to of_get_mac_address") it is now possible to get a -EPROBE_DEFER return code. Which did cause bgmac to assign a random ethernet address. This exact issue happened on my Meraki MR32. The nvmem provider is an EEPROM (at24c64) which gets instantiated once the module driver is loaded... This happens once the filesystem becomes available. With this patch, bgmac_probe() will propagate the -EPROBE_DEFER error. Then the driver subsystem will reschedule the probe at a later time.

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.
