I do see the point, I'm just trying to understand how to best avoid this issue.
Let's drop the part "remove update_fec_mac_prop()" completely from this
discussion, that's not happening and we agree on that.

I wholeheartedly agree!

I've been pondering about this issue for a while actually. Right now, the
update_fec_mac_prop() unconditionally overwrites the bootloader-passed setting,
yes or am I wrong?

But the device tree given to the kernel should be complete, no?
