If the case of reset timeout, emac_report_timeout_error() function is called to report an error. The problem is this function uses net_device name to report device related, which is not correct, as a result in the kernel log buffer we see: eth%d: reset timeout The solution is to print device_node full_name instead. After applying the patch proposed, error string is like the following: /plb/opb/ethernet@ef600e00: reset timeout Signed-off-by: Mikhail Zolotaryov Acked-by: Benjamin Herrenschmidt Signed-off-by: David S.
