If the make finished without errors, you should have a *.ko file. This needs to go into the directory
Code:
/lib/modules/`uname -r`/kernel/net/wireless/
From there, I believe you simply run "depmod -a", and you should be able to load the driver with a modprobe command, ie 'modprobe 8172'. Somebody correct me if I'm wrong, please, as I'm not 100% on this.
