I have a CL6832 eval board and needed to add some code (lifted from PAO) to initialize the the port address. However, I'm still having trouble with the code in that interrupts don't seem to be working in that I keep getting device timeouts for the ethernet (this happens with PAO and current). We should be getting in a TI eval board and my laptop has the TI1130. So I expect to be doing some hacking on this stuff.
