https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D258757 Bug ID: 258757 Summary: [ix] network driver is loosing packets Product: Base System Version: 12.2-RELEASE Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: vdruginin@gmail.com The ix network driver is loosing packets. I ping from host 192.168.205.98 to host 10.0.2.92 trhough freebsd gateway. This is destination host interface: dvg@gw:/usr/local/etc# tcpdump -ni vlan7 host 10.0.2.92 tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on vlan7, link-type EN10MB (Ethernet), capture size 262144 bytes 10:33:20.881990 IP 192.168.205.98 > 10.0.2.92: ICMP echo request, id 10, se= q 1, length 64 10:33:20.882201 IP 10.0.2.92 > 192.168.205.98: ICMP echo reply, id 10, seq = 1, length 64 10:33:21.890452 IP 192.168.205.98 > 10.0.2.92: ICMP echo request, id 10, se= q 2, length 64 10:33:21.890656 IP 10.0.2.92 > 192.168.205.98: ICMP echo reply, id 10, seq = 2, length 64 10:33:22.914468 IP 192.168.205.98 > 10.0.2.92: ICMP echo request, id 10, se= q 3, length 64 10:33:22.914684 IP 10.0.2.92 > 192.168.205.98: ICMP echo reply, id 10, seq = 3, length 64 10:33:23.938468 IP 192.168.205.98 > 10.0.2.92: ICMP echo request, id 10, se= q 4, length 64 10:33:23.938688 IP 10.0.2.92 > 192.168.205.98: ICMP echo reply, id 10, seq = 4, length 64 As we can see the replies are in the place. The source interface: dvg@gw:/usr/local/etc# tcpdump -ni vlan205 host 10.0.2.92 tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on vlan205, link-type EN10MB (Ethernet), capture size 262144 bytes 10:34:33.570316 IP 192.168.205.98 > 10.0.2.92: ICMP echo request, id 10, seq 72, length 64 10:34:34.594365 IP 192.168.205.98 > 10.0.2.92: ICMP echo request, id 10, seq 73, length 64 10:34:35.618334 IP 192.168.205.98 > 10.0.2.92: ICMP echo request, id 10, seq 74, length 64 10:34:36.642349 IP 192.168.205.98 > 10.0.2.92: ICMP echo request, id 10, seq 75, length 64 ^C As we can see the replies are lost. All firewalls are disabled. The problem has gone when I swithed to 1G igb interfaces on the gateway.
