Near all do optionally, but it would make increasing the statistics a magnitude more expensive. Atomic operations don't come cheap on modern systems. And you would need to change the fast path increments to atomic for this. I suspect it could be done without atomics with some tricks (e.g. use a double set of counters and switch on clear and use RCU), but it would make the whole thing quite complex and still have more overhead in the fast path than the current code. -Andi - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
