I disagree that we should bother about clearing statistics. It always
adds more complication than necessary. Few (if any) other statistics in
Linux permit easy clearing, often because adding operations other than
'increment' or 'read' requires adding expensive spinlocks or atomic
operations.
Every networking device in the world supports clearing interface statistics.
Why should linux not be able to do the most basic operation on any
cisco/juniper/enterasys/whatever managed switch or router?
AFAIK, note that clearing interface statistics on such routers doesn't
clear SNMP statistics, just the statistics available through CLI. So
you really have two levels of statistics, and I suspect clearing
"slave" statistics shouldn't be too difficult to implement.
