I've seen articles describing how to disable LAN on the RPi 1 Model B. But it's not working on my RPi 2 Model B. According to Disable LAN9512 the command is supposed to be:
echo 0x0 > /sys/devices/platform/bcm2708_usb/buspower to disable it, but that doesn't work on my device as I don't have the bcm2708_usb part.
Here is an output of ls -l /sys/devices/platform/
pi@raspberrypi /sys/devices/platform $ ls -l

I'm looking for a solution to disable the LAN because my aim is to turn off the chip that provides power to the LAN as I would like to run a test to utilise the cpu only and measure its power consumption.
