    net: dsa: mediatek: add VLAN support for MT7530 · 83163f7d
    Sean Wang authored
    MT7530 can treat each port as either VLAN-unaware port or VLAN-aware port
    through the implementation of port matrix mode or port security mode on
    the ingress port, respectively. On one hand, Each port has been acting as
    the VLAN-unaware one whenever the device is created in the initial or
    certain port joins or leaves into/from the bridge at the runtime. On the
    other hand, the patch just filling the required callbacks for VLAN
    operations is achieved via extending the port to be into port security
    mode when the port is configured as VLAN-aware port. Which mode can make
    the port be able to recognize VID from incoming packets and look up VLAN
    table to validate and judge which port it should be going to. And the
    range for VID from 1 to 4094 is valid for the hardware.
