Or perhaps the driver needs a way to tell userspace what update frequency it should expect? Without some kind of coordination, we have the present silly situation: userspace network activity monitors are checking rx_bytes more frequently than could possibly be useful. Do different Ethernet drivers update rx_bytes at the same rate? Or is this completely ad hoc?
