BUT I don't think I didn't setup *silly* situation. my customers who are reporting this problem, running firewall on linux which is forwarding packets with high rate. I don't want to say 'don't ifconfig down, don't reboot, don't shutdown' it would introduce problem on your such *sily* sitution'. In addition, my laptop is just connected to another *linux* machine which is generating 300mbps 64byte udp packets infinitely.
