For one quite a few of the network cards keep the stats in hardware and
don't neccessarily have a way to reset them. In other cases there is a
mix of OS accumulated stats bulk updated by overflow events on the device
itself.

Its a lot of complexity, and changes all over the places for the sake of
a trivial userspace change. I would suggest you instead write a quick bit
of perl or python that fetches the stats and then updates every second
with the changes.
