I would suggest that parsing the output from ifconfig, ip, or even / 
proc/net/dev should be deprecated -- over the years parsing the output  
of ifconfig has always been broken eventually, and there's no reason  
think iproute2 will be any better.

The format of /proc/net/dev is somewhat less likely to change, but all  
the statistics it provides are available in a pre-digested form at:
	/sys/class/net/<interface_name>/statistics/<statistic_name>
which seems easier to read and should be more robust even if new  
statistics are added.
