The de1soc_r1_pdata sets is_100_mbits to true. The PHY modes declared in the capabilities are MII, RGMII and GMII. GMII doesn't support 100Mbps, and as for RGMII, it would be a bit implausible to me to support this PHY mode but limit it to only 25 MHz. So I've settled on MII as a phy-mode in the example, and a fixed-link of 100Mbps. As a side note, there exists such a thing as "rev-mii", because the MII protocol is asymmetric, and "mii" is the designation for the MAC side (expected to be connected to a PHY), and "rev-mii" is the designation for the PHY side (expected to be connected to a MAC). I wonder whether "mii" or "rev-mii" should actually be used here, since this is a CPU port and presumably connected to another MAC.
