The DE2-115 board provides Ethernet support via two Marvell 88E1111 Ethernet PHY chips. The
88E1111 chip with integrated 10/100/1000 Mbps Gigabit Ethernet transceiver support
GMII/MII/RGMII/TBI MAC interfaces.
Figure 4-27
Here only RGMII and MII modes are supported on the board (The factory default mode is RGMII).
There is one jumper for each chip for switching work modes from RGMII to MII (See
