new version:

This one prototypes incrementing counters for VLAN devices (rx/tx,
packets and bytes). Counters for netdevices representing physical ports
should be managed by the NIC driver.

I will look at what can be done for packet captures (e.g., xdpdump and
https://github.com/facebookincubator/katran/tree/master/tools). Most
likely a project for next week.
