The DCF needs to query the VLAN capabilities based on current device configuration firstly. DCF is able to configure inner VLAN filter when port VLAN is enabled base on negotiation; and DCF is able to configure outer VLAN (0x8100) if port VLAN is disabled to be compatible with legacy mode. When port VLAN is updated by DCF, the DCF needs to reset to query the new VLAN capabilities.
