If anyone has any objections, please let me know. ------------------ [ Upstream commit e5ebe63214d44d4dcf43df02edf3613e04d671b9 ] /sys/class/net//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.
