I will answer my own question.
The project was not set up correctly from MXCube. Comparing a similar project found on

http://www.carminenoviello.com/2016/01/22/getting-started-stm32-nucleo-f746zg/

the resources for lwip were not completely configured. Once I got it fully configured also using FreeRTOS, config.h is in the project.

However it still falis to compile:
Description Resource Path Location Type
make: *** Middlewares/LwIP/init.o Error 1 Hello_Ethernet C/C++ Problem
Description Resource Path Location Type
redefinition of ‘struct timeval’ Hello_Ethernet line 313, external location: C:\Users\Greg\workspace\AC6\necleo-f429ZI\Hello_Ethernet\Middlewares\Third_Party\LwIP\src\include\lwip\sockets.h C/C++ Problem

When I implemented FreeRTOS I was warned in MXCube regarding the use of systick as a time base source for SYS with the OS selection. I switched the source to TIM1. I am not sure if this has any bearing on what I am seeing. Not even sure if TIM1 is the correct choice since there is a lack of guidence.

Still waiting to know if anyone has gone down this path before.
