Hi!
NeTraMet v44b10 uses pcap(3) and complains about timestamps jumping backwards. Looks like a PF_PACKET socket doesn't receive the packets in the correct order. Some timestamps from a "tcpdump -tt":
RX: 1001465480.175100 [...] TX: 1001465480.179111 [...] RX: 1001465480.177315 [...] ^^^^^^ TX: 1001465480.180514 [...] RX: 1001465480.179706 [...] Some more figures (obtained with a quick hack using libpcap-2001.09.25 on two different machines):
2.2.19: stats: 100000 packets received 0 packets dropped good: 90222 packets bad: 9778 packets max delta: 15850 usec
2.4.1: stats: 100000 packets received 0 packets dropped good: 99538 packets bad: 462 packets max delta: 471 usec Any plans to fix this in the kernel?
Regards, Joerg
