25d3b493a52d ("bridge: Fix inability to add non-vlan fdb entry") might
be what you are looking for, but you might want to do git-bisect to
track down any regression or fix.

If 25d3b493a52d is causing your problem, set default_pvid to 0 in order
to disable default_pvid, and delete any vlans which is already
configured in bridge's vlan_filtering. Then, delete the fdb entry.
