Hi,
Thank you for your reply, it worked and we are able to test it.
one more issue we are facing if u can help it will be good.

In u-boot we added an environment setting to disable gigabit advertising for our makerboard version.
In som.c, you can remove the ifdef and it will always set disable_giga. Jonathan Cormier

Hi,
How can we change speed of the Ethernet link from "1Gbps/full" to "100Mbps/full" as in "Link is Up - 1Gbps/Full - flow control rx/tx" .
is it in driver code or dts file after kernel is bought up.
