Hi schumaku ,
Those messages are used by ATPD for HGW and Wifi bridge discovery.
Wireshark recognize the destination address as Dst: Spanning-tree-(for-bridges)_ef:03:fe. However it marks protocol type as Unknown (0xfe68) and not an STP

If you don't need STP, you could try to disable it, and enable the "Forward BPDU while STP disabled", this exists AFAIK on the M4100 series, too.
I would expect they handle/filter the STP protocol based on src and dst address, not on the protocol number.
