bonding: set carrier off for devices created through netlink
[ Upstream commit 005db31d5f5f7c31cfdc43505d77eb3ca5cf8ec6 ] Commit e826eafa65c6 ("bonding: Call netif_carrier_off after register_netdevice") moved netif_carrier_off() from bond_init() to bond_create(), but the latter is called only for initial default devices and ones created through sysfs: $ modprobe bonding $ echo +bond1 > /sys/class/net/bonding_masters $ ip link add bond2 type bond $ grep "MII Status" /proc/net/bonding/* /proc/net/bonding/bond0:MII Status: down /proc/net/bonding/bond1:MII Status: down /proc/net/bonding/bond2:MII Status: up Ensure that carrier is initially off also for devices created through netlink.
