Ok.
I might have missed something but why can’t an ESP32 or some other microcontroller be used as a hardware tool to more easily construct low level frames?
The ESP32 would still be connected to a Linux machine to control it.
I’m not a security researcher so I don’t know how this work is normally done. My simplistic take is if the OS and drivers make some of this hard I would look for a simpler environment that I had more control over.
Or it that too naive an approach?
