As I see there is already the way with Kconfig option, with previous
broadcom/mellanox get mac address and set affinity for mellanox commands.
I'm not sure about dts based solution. As I see there is two ways:
1. make everything related OEM into dts based options
2. or this way, with Kconfig

I like the idea, it may help with debugging.
