Subject: [PATCH 058/135] qeth: initialize net_device with carrier off
[ Upstream commit e5ebe63214d44d4dcf43df02edf3613e04d671b9 ]
/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.
