commit e5ebe63214d44d4dcf43df02edf3613e04d671b9 Author: Ursula Braun <ubr...@linux.vnet.ibm.com> Date: Fri Dec 11 12:27:55 2015 +0100 qeth: initialize net_device with carrier off /sys/class/net/<interface>/operstate for an active qeth network interface offen shows "unknown", which translates to "state UNKNOWN in output of "ip link show". It is caused by a missing initialization of the __LINK_STATE_NOCARRIER bit in the net_device state field. This patch adds a netif_carrier_off() invocation when creating the net_device for a qeth device.
