Link problem after boot with 21.02

Installing and Using OpenWrt Network and Wireless Configuration
1

Hello,
after updating to 21.02 on wrt3200acm I have problems with my connection.
Every time I start my router, the lan ports do not connect. I have to unplug my lan cable and plug it back in. After that the connection comes up again.

I use a taged vlan on the lan ports and a firewall.

Here is my dmesg output after boot:

Did you reset the configuration? It looks like you are using the old vlan config from v19.
v21 switched to DSA and doesn't use vlans anymore.

I have completely redone the configuration. So this should not be a update process fault.

I found some more information.
After booting all vlan ports have no IP's. Even though all port have a static IP's in the config files. (The "Force Link" is disabled.)

There is no kernel module that will be loaded after putting the cable into the port.

After all I have no ideas where I could search for the problem.

I will write down what I have done for the Vlan configuration.

  1. Under Network -> Interface -> Device: make a new unmanaged bridge (no IP) with all four LAN ports in it. New Device Name "br-lan"
  2. Under Network -> Interface -> Device: make a new 802.1q device on the base device from 1) and give him a VLAN-ID. New Device Name will be "br-lan.VLANID"
  3. more VLAN-Devices
  4. Under Network -> Interface -> Device: edit config of br-lan in the tap "Bridge VLans filtering". Building tagged and untagged VLan-IDs
  5. Under Network -> Interface: Create new Devices with static IPs on the Device "br-lan.VLANID".

Think that's all.
Maybe you see a mistake or a hint or something?

If I restart the network with "/etc/init.d/network restart" the device will come up.
