Autoneg off in TI cpsw driver

Hi,

I am using a Linux Kernel 4.1 Kernel. on AM437X with dual emac configuration.

What i find is if i do the following the Link does not come up.

1. run ethtool -s eth1 speed 10 duplex full autoneg off
2. remove cable
3. plug it in.

With the above sequence. The link does not come up. the plug in is not detected

Am i missing something or is this the default behaviour.

Regards,
Sriram
