Subject: Assigning MAC addrs to PCI based NIC's

Greetings,

We make embedded boards that often have on-board PCIe based NIC's that
have MAC addresses stored in an EEPROM (not within NIC's NVRAM). I've
struggled with a way to have boot firmware assign the mac's via
device-tree and I find that only some drivers support getting the MAC
from device-tree anyway.

What is the appropriate way to assign vendor MAC's to a NIC from boot
firmware, or even in userspace?

Best regards,

Tim
