Thats the point atm, currently this would not work because of dcdbas module. 

I already contacted the Dell developers to fix the driver. There is the uevent 
for the device missing. I await they fix it soon. Then it would work out of 
the box.

Since there is already a fix for the driver to support DMI autoload the module 
on all Dell systems it should work out of the box on newer kernels anyway.

At least the change for the KillSwitch devices would prevent NetworkManager 
from poll the interface also if the driver isn't loaded.
