Broken 802.11r Fast Transition / Roaming and 5Ghz issues probably caused by DSA implementation

Quick Update

Hello OpenWrt Community,

I wanted to provide a quick update on the bugfix concerning the lowering of aging time of bridge containing vlans for WiFi roaming. Unfortunately, it appears that the temporary bugfix is no longer working in OpenWrt versions:

  • 23.05.0-rc4
  • SNAPSHOT - r24054-fe10f97439

Reverting to an older OpenWrt version was the only option for me:

  • SNAPSHOT - r23930-6cf27094e9

Observed Behavior

A FDB entry hangs on the second device, as indicated below:

??:??:??:??:??:?? dev sw-eth1 vlan 10 self

This behavior leads to a connectivity interruption lasting approximately 5 minutes (while the entry exists).

Regards,
David
