Its not needed. But the SD card users tend to flash the exact same image (from a PC) to multiple SDs, therefore cloning the mac address.
If your devices are already using different mac addresses, don't worry.

Thanks for clarify.

I just flashed an S9J with ssh image successfully and am going to do the rest of my miners

Need a little help here,
At the end of the operation it print out "Content of U-Boot configuration" as bellow:

Code:

And then:

Code:

Upgrade was successful!

Where can I find "U-Boot configuration" to edit so I dont need to manually edit all the other miners after flash.
