I say the best way to get things up and running with the TSE MAC is to use a NIOS with the simple socket server example. There is debug code in there to inform you if your MAC was found or not.

However, did you enable the MDIO interface when you configured the TSE MAC? Also, did you properly set the clock divisor for the MDIO clock?
