bonding: fix active-backup transition after link failure
After the recent fix in commit1899bb3251
("bonding: fix state transition issue in link monitoring"), the active-backup mode with miimon initially come-up fine but after a link-failure, both members transition into backup state. Following steps to reproduce the scenario (eth1 and eth2 are the slaves of the bond): ip link set eth1 up ip link set eth2 down sleep 1 ip link set eth2 up ip link set eth1 down cat /sys/class/net/eth1/bonding_slave/state cat /sys/class/net/eth2/bonding_slave/state Fixes:1899bb3251
