So because some (in the case of a core router almost none) of the packets will need a timestamp, you do it for every single one of them? This sounded so unbelievable to me that I took a quick look at the code to see what I'd have to do to get rid of it. It appears that gettimeofday is not called for every packet; just for ICMP timestamp requests and for IP options (ip_options_build and ip_options_compile). -Ralph - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
