Javier,
Yes, I have got the state machine running for link monitoring. However, I am not enabling or routing the link status interrupts.
I have gotten questionable results from polling the LINK register in the MDIO module, but was going to save that issue for a separate future forum post (problem is very similar to this post: http://e2e.ti.com/support/dsp/c6000_multi-core_dsps/f/639/t/167106.aspx).
