Even without the KERNEL== doesn't seem to work:

I'm testing this by first removing the network device (ex. rmmod
e1000), so I can have first an ADD event and then a REMOVE event, by
removing again the module, so:

rmmod e1000 (remove first)
modprobe e1000 (ADD event, set the test_device var to 1)
rmmod e1000 (REMOVE event, get the test_device value)

This doesn't seem to work, or at least it looks like that.
