[24.10.0-rc2] batman problems with VLAN on R7800

Describe the bug

The R7800 moved from swconfig to dsa and needed to be reconfigured. I setup batman and it worked properly connecting to my network on vlan 4 over WiFi. After a reboot it lost access to batman and I have lots of log entries with: Wed Dec 4 12:33:43 2024 kern.info kernel: [ 684.643416] batman_adv: bat0: adding TT local entry xx:xx:xx:xx:xx:xx to non-existent VLAN 4

Restarting the "lan" interface fixes the problem until I reboot again. The "lan" interface is attached to device "br-lan.4". Device "br-lan" has "bat0" in bridge ports with "bat0" getting VLAN 4 tagged on the VLAN filtering tab.
