netstat -i still digs into kernel memory to get those stats, I think,
so you can't directly access those numbers as a regular user.  You can
shell out and parse the output of "netstat -i", or do some snmp queries
to your local net-snmp daemon.  Checking the dev.em.0.stats sysctl node
is another option, and gives you some more hardware status counters
than netstat, but not all drivers support it (em does so you're okay).
