How to enable default hardware wifi mac address?

dewet

Hi

I want to set the wifi mac address to the default hardware mac address.
So if I flash firmware to 5 different devices, each have their own unique wifi mac address.
And when device is rebooted it should retain the same mac address and not get a random one again.

Don't want to manually set wifi mac address for each device in dts file or Upgradedl tool to flash custom mac to each device.
I want to use the hardware mac address build into the hardware.

What files need to be changed in kernel /drivers/wifi?
Any options to set in kernel .config file to build hardware mac address?

Also for ethernet mac?

Anyone that can help?
