DP83640: DP83640

Currently we have configured DP83640 with linux kernel 3.12 and it is working. I am getting ping response. But in case of TI kernel 4.1.141 we have connected same way but we are not getting any ping response.

Also I have done configuration in the menuconfig also.

I have also done DTS configuration. Below is the DTS Configuration

Please look in to this. Do i have to make some modification in the same. Please let me know.
