When AM437x EVM is connected to Gigabit switch, it takes more time to finish auto-negotiation than on a 10/100 switch.
The default 4 second limit times-out more often than not. This is observed when testing with a D-Link DGS-1008A desktop switch.
Increase the auto-negotiation time-out for AM437x EVM to handle this case.
