- * The GW16083 interfaces with a Ventana baseboard via the PCIe bus, an i2c
- * bus (i2c2), and a couple of GPIO's. On the PCIe bus is an i210 GigE with
- * its MAC connected to Port4 of a Marvell MV88E6176 7-port GigE switch via
- * MDIO and RGMII. Ports 0-3 are standard copper RJ45 but Ports 5 and 6
- * connect to Marvell MV88E1111 dual-mode Copper/Fiber PHY's over SGMII and
- * MDIO. The PHY's have both an RG45 for copper and an SFP module.
