Cannot get VLAN working Xiaomi AC2100

Installing and Using OpenWrt
1

Hello Guys,
i desperate to get VLAN 802.1Q working on Xiaomi AC2100 (MediaTek MT7621). I compiled OpenWRT fresh from Snapshot and i also tested tag/v21.02.0-rc3. Everytime i configure VLAN on the predefined 'br-lan' device i instant lose the connection an luci want to revert the changes after 90 seconds.
Does anybody have an working configuration file or an hint whats going on? In the systemlog there are no fatal errors i think:

Hello,

i figured out an "solution". Threrfore is use the router only as an access point this is okay for me. But the problem should be fixed in code.

I figured out that the current version i broken. If you want to commit the vlan settings the router is rebooting an revert everything to the stock settings.
Step #1. Checkout this commit, compile and flash:

git checkout 479a2a90f782209b29dd9746d241fc1e67836309

Step #2. Configure your vlans manual with the dsa syntax similiar like my example:


config interface 'loopback'
	option device 'lo'
	option proto 'static'
	option ipaddr '127.0.0.1'
	option netmask '255.0.0.0'

config globals 'globals'
	option packet_steering '1'
	option ula_prefix 'fd6e:b8da:b0cc::/48'

config device
	option name 'br-lan'
	option type 'bridge'
	list ports 'wan'
	list ports 'lan1'
	list ports 'lan2'
	list ports 'lan3'

config interface 'lan'
	option device 'br-lan'
	option proto 'static'
	option netmask '255.255.255.0'
	option ip6assign '60'
	option ipaddr '192.168.1.8'

config interface 'vlan20'
	option proto 'none'
	option device 'br-vlan20'

config device
	option name 'br-vlan20'
	option type 'bridge'
	list ports 'wan.20'
	list ports 'lan1.20'
	list ports 'lan2.20'
	list ports 'lan3.20'

config interface 'vlan4094'
	option proto 'none'
	option device 'br-vlan4094'

config device
	option name 'br-vlan4094'
	option type 'bridge'
	list ports 'wan.4094'
	list ports 'lan1.4094'
	list ports 'lan2.4094'
	list ports 'lan3.4094'

then it should work!
Let me know if you need the firmware precompiled i have the binaries.
Maybe i have free time to investigate this in code but in the moment i works.

Best regards
