It's hard for me to understand how applying only patch "tag_mtk only
combine VLAN tag with MTK tag is user port is VLAN aware" can produce
the results you describe... For packets sent to port lan0, nothing
should have been changed by that patch, because dsa_port_is_vlan_filtering(dp)
should return true.

If you can confirm there isn't any mistake in the testing procedure,
I'll take a look later today at the hardware documentation and try to
figure out why the CPU port is configured the way it is.

booted an older kernel without your patches, and tried the vlan-aware bridge the same way,
and it is not working there too. So not broken with your patches.

this is how i have created the bridge completely (to exclude a mistake in my setup):

BRIDGE=lanbr0
ip link add name ${BRIDGE} type bridge vlan_filtering 1 vlan_default_pvid 1
ip link set ${BRIDGE} up
ip link set lan0 master ${BRIDGE}
ip link set lan0 up

ip link add link lanbr0 name lanbr0.100 type vlan id 110
ip a a 192.168.110.5/24 dev lanbr0.100
ip link set lanbr0.100 up

btw. why is my vlan software-only and not pushed to hardware?
