The KSZ9477 is a fully integrated layer 2, managed, 7 ports GigE switch with numerous advanced features. 5 ports incorporate 10/100/1000 Mbps PHYs. The other 2 ports have interfaces that can be configured as SGMII, RGMII, MII or RMII. Either of these may connect directly to a host processor or to an external PHY. The SGMII port may interface to a fiber optic transceiver. This driver currently supports vlan, fdb, mdb & mirror dsa switch operations.
