Looks reasonable to me.  As an aside I am fairly certain that Ubuntu
patched sys to be the default backend some time ago, and we should
probably just remove the nettools backend code entirely.

Long term it would be interesting to hook knemo into the TDE hardware
library (which already monitors statistics via sysfs) to reduce code
duplication.
