Adding a new module that tracks the number of bytes/packets transfered by a network interface, even after the interface has been removed.
This is relevant to track the total data usage in mobile devices whose interfaces are added and removed quite frequently (WiFi, Bluetooth, 3G,..).
Monitoring is done only for devices that are configured with a valid IP address (check to exclude virtual/loopback/tunnel interfaces).
