Planned network structure will be as with 4.7.x kernels:

br0 <=> eth0.101 <=> eth0 (vlan 101 tagged) <=> lan 1-lan4 (vlan 101
untagged pvid)

br1 <=> eth0.102 <=> eth0 (vlan 102 tagged) <=> wan (vlan 102
untagged pvid)
Do you even need these vlans?
Yes, remember, b53 does not currently turn on Broadcom tags, so the only
way to segregate traffic is to have VLANs for that.

Are you doing this for port separation? To keep lan1-4 traffic
separate from wan? DSA does that by default, no vlan needed.

So you can just do

ip link add name br0 type bridge
ip link set dev br0 up
ip link set dev lan1 master br0
ip link set dev lan2 master br0
ip link set dev lan3 master br0
ip link set dev lan4 master br0

and use interface wan directly, no bridge needed.
That would work once Broadcom tags are turned on which requires turning
on managed mode, which requires work that I have not been able to get
done :)
Setup with swconfig:



# Delete all IP addresses and get link up
ip addr flush dev ${INTERFACE}
ip link set ${INTERFACE} up

# Lamobo R1 aka BPi R1 Routerboard
# Speaker | LAN1 | LAN2 | LAN3 | LAN4 || LAN5 | HDMI
# SW-Port |  P2  |  P1  |  P0  |  P4  ||  P3  |
# VLAN    |  11  |  12  |  13  |  14  ||ALL(t)|
# Switch-Port P8 - ALL(t) boards internal CPU Port

# Setup switch
swconfig dev ${INTERFACE} set reset 1
swconfig dev ${INTERFACE} set enable_vlan 1
swconfig dev ${INTERFACE} vlan 101 set ports '3 8t'
swconfig dev ${INTERFACE} vlan 102 set ports '4 0 1 2 8t'
swconfig dev ${INTERFACE} set apply 1

How to achieve this setup CURRENTLY with DSA?
Your first email had the right programming sequence, but you did not
answer whether you have CONFIG_BRIDGE_VLAN_FILTERING enabled or not,
which is likely your problem.
Here are some reference configurations that should work:

I know, some comments are from me but none of them worked, therefore on LKML :-)


so this can't be the issue, any further ideas?

On my 2nd Banana Pi-R1 still on Fedora 25 with kernel 4.12.8-200.fc25.armv7hl the commands still work well, but I wanted to test the upgrade on another one.
