The third port is an RMII/MII interface to a host\n+master network interface (e.g. fixed link).\n+\n+\n+Driver details\n+==============\n+\n+The driver is implemented as a DSA driver, see\n+Documentation/networking/dsa/dsa.txt.\n+\n+See Documentation/devicetree/bindings/net/dsa/lan9303.txt for device tree\n+binding.\n+\n+The LAN9303 can be managed both via MDIO and I2C, both supported by this driver.\n+\n+At startup the driver configures the device to provide two separate network\n+interfaces (which is the default state of a DSA device). Due to HW limitations,\n+no HW MAC learning takes place in this mode.\n+\n+When both user ports are joined to the same bridge, the normal HW MAC learning\n+is enabled. This means that unicast traffic is forwarded in HW. Broadcast and\n+multicast is flooded in HW. STP is also supported in this mode. The driver\n+support fdb/mdb operations as well, meaning IGMP snooping is supported.\n+\n+If one of the user ports leave the bridge, the ports goes back to the initial\n+separated operation.\n+\n+\n+Driver limitations\n+==================\n+\n+ - Support for VLAN filtering is not implemented\n+ - The HW does not support VLAN-specific fdb entries\n","prefixes":["net-next"]}
