[PATCH net-next v1 0/6] net: dsa: mt7628: add VLAN filtering support

[Joris Vaisvila <joey@tinyisr.com>]

Add bridge offload and VLAN filtering support to the MT7628 switch.

The MT7628 switch uses VLAN membership as its forwarding mechanism. This
series uses tag_8021q VLANs to emulate VLAN-unaware bridge forwarding,
while using the bridge's VLAN configuration directly when VLAN filtering
is enabled. A major limitation is that VIDs cannot be reused between
separate bridges, as this would allow cross-bridge forwarding. tag_8021q
VIDs are also reserved for the same reason.

The switch driver adds 6x "reserved" VLAN slots for use by tag_8021q
that are only programmed on VLAN-unaware ports, together with double
tagging, while the remaining slots are only programmed for VLAN-aware
ports.

The tagger is updated to preserve the existing VLAN tags on transmit and
receive.

Thanks,
Joris
