DSA and its drivers currently hook the NETDEV_CHANGEUPPER net_device event in order to configure the VLAN map of every port.
This VLAN map is a feature of these switch chips to hardcode and restrict which output ports a given input port can egress frames to. A Linux bridge is a simple untagged VLAN propagated by the bridge code itself. With a proper 802.1Q support, a driver does not need this hook anymore, and will simply program the related VLAN object. This patchset improves the hardware bridging code in the mv88e6xxx driver with a strict 802.1Q mode. Ideally, the equivalent must be done for Broadcom Starfighter 2 and Rocker, before completely getting rid of this hook.
