gianfar: ethernet vanishes after restoring from hibernation
If a gianfar ethernet device is down prior to hibernating a system, it will no longer be present upon system restore. For example: ~# ifconfig eth0 down ~# echo disk > /sys/power/state <trigger a restore from hibernation> ~# ifconfig eth0 up SIOCSIFFLAGS: No such device This happens because the restore function bails out early upon finding devices that were not up at hibernation. In doing so, it never gets to the netif_device_attach call at the end of the restore function. Adding the netif_device_attach as done here also makes the gfar_restore code consistent with what is done in the gfar_resume code.
