Where to install files for USB-to-RJ45 on Android?

[AC Question]

I've got a USB-to-RJ45 connector that you plug into your Android device and then plug a RJ45 into an adaptor (I work at an outpost with no wireless internet). I have to install some files in order to make it work but I cannot figure out where to put it on an Android device.

These are the files:
50-usb-realtek-net.rules
compabtibility.h
Makefile
r8152.c

Any help is much appreciated!
