Linux/AM3358: AM335x Network identification issue with SDK v2.00.00.00

Part Number: AM3358

Tool/software: Linux

We develop one products based on TI AM-3358.　Before, when we use the TI Linux SDK 06.00.00.00, the gigabit network can work properly.  Now we want to update the Linux to TI Linux SDK v2.00.00.00 and encounter problems.  The network port access 1000M network is always non-stop printing the following message.

[ 1406.269359] cpsw 4a100000.ethernet eth1: Link is Up - 1Gbps/Full - flow control off
[ 1408.269205] cpsw 4a100000.ethernet eth1: Link is Down
[ 1410.269327] cpsw 4a100000.ethernet eth1: Link is Up - 1Gbps/Full - flow control off
[ 1412.269174] cpsw 4a100000.ethernet eth1: Link is Down

The number of prints per time is not fixed and the network can not be used. Until printing the following message the network can be used normally.

[ 1417.269374] cpsw 4a100000.ethernet eth1: Link is Up - 100Mbps/Full - flow control off

So we want to determine why the gigabit network is always identified as a hundred trillion network, and why the gigabit network can not be used normally.
