Date: Fri, 27 Apr 2007 16:53:41 -0400 From: "Tim Durack" <tdurack@...il.com> To: "Francois Romieu" <romieu@...zoreil.com> Cc: netdev@...r.kernel.org Subject: Re: r8169 ethernet bonding problems > See: > http://www.fr.zoreil.com/linux/kernel/2.6.x/2.6.21-rc7/ > > Please Cc: netdev on success/failure. Applied suggested patchset to vanilla 2.6.21. Compiled using .config from linux-image-2.6.21-rc7 pulled down from http://kernel-archive.buildserver.net/debian-kernel Compiles, boots. Bonding does not work reliably. Simple config: #auto bond0 iface bond0 inet manual up ip link set dev $IFACE up up echo +eth1 > /sys/class/net/$IFACE/bonding/slaves up echo +eth2 > /sys/class/net/$IFACE/bonding/slaves up ip link set dev eth1 up up ip link set dev eth2 up up ip addr add 172.21.255.5/29 dev $IFACE down ip addr del 172.21.255.5/29 dev $IFACE down ip link set dev eth2 down down ip link set dev eth1 down down echo -eth2 > /sys/class/net/$IFACE/bonding/slaves down echo -eth1 > /sys/class/net/$IFACE/bonding/slaves down ip link set dev $IFACE down Bond comes up, cannot ping unless I manually force promisc on both member links: ip link set dev eth1 promisc on ip link set dev eth2 promisc off Link failover does not work reliably. Carrier-detect appears to be working, so I don't think that is an issue. A disturbing problem is mac corruption after "modprobe -r r8169; modprobe r8169" ip link sh: 2: eth5: <BROADCAST,MULTICAST> mtu 1500 qdisc noop qlen 1000 link/ether 00:00:00:00:68:93 brd ff:ff:ff:ff:ff:ff 3: eth1: <BROADCAST,MULTICAST> mtu 1500 qdisc pfifo_fast qlen 1000 link/ether 00:30:18:ab:68:94 brd ff:ff:ff:ff:ff:ff 4: eth2: <BROADCAST,MULTICAST> mtu 1500 qdisc noop qlen 1000 link/ether 00:30:18:ab:68:95 brd ff:ff:ff:ff:ff:ff eth5 mac was 00:30:18:ab:68:93 before the modprobe. Not sure what's going on here, but I'm starting to think these interfaces aren't the best in the world...
