Which also are snmp stats. So far the reasoning of why this is needed has been around debugging which is in itself reasonable as long as it doesnt break things: it does. For debugging: I can name about 3 ways you can achieve the counting without touching the driver/hardware level stats. Someone needs to put effort and create a tool to it. [ Actually now that i spent 2 minutes looking at the patch i can understand jgarziks concerns].

It may be insufficient. Management tools use the resetting as a trigger to indicate rollover of the counters. I dont know if you can go and fix everyone out there to have this new ztime in mind. Can you ask internally on how openview would handle this? It carriers the major chunk of management tools market so it may provide good insight.
