Have you looked through the wealth of information available from TI on the DP83640? - see here (http://www.ti.com/product/dp83640/technicaldocuments). Configuration is done over the Serial Management Interface - the MDC & MDIO pins. 

 Have you considered Altera's own Triple-speed MAC IP for interfacing to the Phy? Do away with the external MAC you mentioned.  Cheers, Alex
