ls1021atwr chip use ethtool to set sgmii net 1000Mpbs speed

[jokerzhou]

 my board is ls1021atwr chip,and input ethtool -s eth0 speed 1000 duplex full autoneg off,but it not successed.eth0 alwags link down.but input ethtool -s eth0 speed 100 duplex full autoneg off or ethtool -s eth0 speed 10 duplex full autoneg off , it can success. And  input ethtool -s eth0 autoneg on, it can link on and speed is 1000.eth0 used sgmii.

I do not kown what is wrong with this. can you help me?
