Gigabit Ethernet Interface (via Marvell 88E1111) with Cyclone IVE FPGA

Yes sorry, I somewhat missed your first post where you said you were using the DE2-115.

It doesn't look like the CD contents are available on Altera's web site (contrary to the non-education development kits) so I can't have a look. But on the board's page (http://www.altera.com/education/univ/materials/boards/de2-115/unv-de2-115-board.html), there seems to be a tutorial in PDF about setting up Altera's TSE: ftp://ftp.altera.com/up/pub/altera_material/12.1/tutorials/de2-115/using_triple_speed_ethernet.pdf (and design files here: ftp://ftp.altera.com/up/pub/altera_material/12.1/tutorials/de2-115/using_triple_speed_ethernet_on_de2_115_design_files.zip ). It's strange they didn't think about putting those on the kit's CD.
