Currently, memory usage of UDP can be observed as the sam of usage of tx_queue and rx_queue. But I believe that the system wide accounting is usefull when heavy loaded condition. In the next step, I would like to add memory usage quota for UDP to avoid unlimited memory consumption problem under DDOS attack. This patch set is for 2.6.23-rc7. Unfortunately, I don't have any NIC with UFO. So this patch set is not tested with UFO supported device. I appreciate your comment/test/feedback. Satoshi Oshima
