Hi,

update on my tests...something in my systemd-networkd breaks vlan on dsa-port.

if i boot with this disabled vlan added manually works on dsa-port and gmac too. so felix you can keep my tested-by.

if vlan is working and i activate networkd afterwards vlans are still working...i guess systemd puts the wan-interface into some kind of non-vlan-mode (vlan-filtering?).

this is my basic systemd-config:

/etc/systemd/network/15-wan.network
[Match]
Name=wan

[Network]
BindCarrier=eth0

#static setup
Address=192.168.0.19/24
Gateway=192.168.0.10
DNS=192.168.0.10

IPForward=yes

/etc/systemd/network/20-lanbr.netdev
[NetDev]
Name=lanbr0
Kind=bridge

[Bridge]
DefaultPVID=1
VLANFiltering=1
/etc/systemd/network/22-lanbr.network

[Match]
Name=lanbr0

[Network]
BindCarrier=eth0
ConfigureWithoutCarrier=true

Address=192.168.1.1/24
Address=fd00:A::10/64

[DHCPServer]
PoolOffset=100
PoolSize=150

/etc/systemd/network/05-eth0.network
[Match]
Name=eth0

[Network]
DHCP=no
LinkLocalAddressing=no
ConfigureWithoutCarrier=true

/etc/systemd/network/21-lanbr-bind.network
[Match]
Name=lan0 lan1 lan2 lan3

[Network]
Bridge=lanbr0

/etc/systemd/network/10-wan.link
[Match]
OriginalName=wan

[Link]
Name=wan
#MACAddressPolicy=none
#MACAddress=08:22:33:44:55:77

seems only tx is affected on r3, as i see packets on the vlan from my laptop

tcpdump on R3 (e4:b9:7a:f7:c4:8b is mac from laptop):

I don't have a setup to test 6.2 on my MT7986 board right now, but I did
test latest OpenWrt with my changes and couldn't reproduce the issue there.
I checked the diff between my tree and upstream and didn't find any
relevant differences in mtk_eth_soc.c
Not sure what's going on or how to narrow it down further.
