You got me confused by using just "firmware" in the subject.

Yeah...I started by writing this patch with device tree specifically
(of_get_mac_address()), and then later found that there were generic
"device" helpers for this, which can assist with other sorts of
firmware nodes. It was easier to put a name on a device tree patch
than on a "device" patch. I suppose "system firmware" might be a
better description?

useful EEPROM on which to store its MAC address (e.g., for integrated

Use the generic device helper to retrieve the MAC address, and (if
present) honor it above the MAC address advertised by the card.

But this put me back on track ;-)

Let me know if you have a better way to clarify. I can resend with a
slightly modified subject (s/firmware/system firmware/), or let Kalle
