E310: Change MAC Address?

AP

Is there a way to change the mac address of my e310s?  I have imaged
several e310s using the image file in
https://files.ettus.com/binaries/cache/e3xx/meta-ettus-v3.15.0.0/, and they
all have the same MAC address.

On some searching around the web I can see that it is likely that the MAC
address parameter is specified as a U-boot parameter.  I'd like to know
what my options are for changing it.

Thanks,
Andrew

What is that mac address? I'd like to see if it matches mine.

If I recall correctly, the mac address is flashed into the i2c eeprom,
u-boot is supposed to read that and use it. Factory test should set it
up uniquely. But my memories fade. Inspecting the u-boot source might
show us ....

I didn't sift through the ifdef's though.
