[ Upstream commit 2d3db26d78805c9e06e26def0081c76e9bb0b7d6 ]
Currently, if device is in link down status and user uses 'ethtool -s' command to set speed but not specify duplex mode, the duplex mode passed from ethtool to driver is unknown value(255), and the fibre port will identify this value as half duplex mode and print "only copper port supports half duplex!". This message is confusing.
So for fibre port, only the setting duplex is half, prints error and returns.
