Re: [PATCH net-next 0/4] net: dsa: mv88e6xxx: fix hardware bridging

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.

Series applied, thanks Vivien.
