Subject: bonding: set carrier off for devices created through netlink
From: Beniamino Galvani <bgalvani@redhat.com>
[ 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.
