We saw your initial patch posting, you don't need to send this

netdev added to CC:

From: James Cammarata <jimi@xxxxxxxx>

Added the ability to write to /proc/net/dev in order to clear the
interface counters for a given interface. The ability to zero out
counters (especially the error counters) is extremely useful when
troubleshooting interface issues. Now diffed against, and
added some sanity checking.

echo 'net clear-stats ifdev' > /proc/net/dev
Where "ifdev" is the device name you wish to clear.

I don't wish to suggest I don't like the change - I've used similar features on "other oses" in the past, but when something like this has come-up in the past, haven't there been concerns about MIBs and SNMP and whatnot?

rick jones - beforeafter - subtract one set of stats from another...
