====================
net: dsa: mv88e6xxx: implement VLAN filtering

This patchset fixes hardware bridging for non 802.1Q aware systems.

The mv88e6xxx DSA driver currently depends on CONFIG_VLAN_8021Q and
CONFIG_BRIDGE_VLAN_FILTERING enabled for correct bridging between switch ports.

Patch 1/9 adds support for the VLAN filtering switchdev attribute in DSA.

Patchs 2/9 and 3/9 add helper functions for the following patches.

Patchs 4/9 to 6/9 assign dynamic address databases to VLANs, ports, and
bridge groups (the lowest available FID is cleared and assigned), and thus
restore support for per-port FDB operations.

Patchs 7/9 to 9/9 refine ports isolation and setup 802.1Q on user demand.

With this patchset, ports get correctly bridged and the driver behaves as
expected, with or without 802.1Q support.

With CONFIG_VLAN_8021Q enabled, setting a default PVID to the bridge correctly
propagates the corresponding VLAN, in addition to the hardware bridging:

    # echo 42 > /sys/class/net/<bridge>/bridge/default_pvid

But considering CONFIG_BRIDGE_VLAN_FILTERING enabled, the hardware VLAN
filtering is enabled on all bridge members only when the user requests it:

    # echo 1 > /sys/class/net/<bridge>/bridge/vlan_filtering
