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