Yep, /proc interface is the best way to go to get/store
this data.  In 2.5.X it will be sysfs but on 2.4 and below it is proc.

If you need even more stats, you'll need to modify  the network driver
to store that info.  Then create a custome proc interface that will display
the data when a process tries to open the proc file.
