Bezüglich Vincenzo Maffione's Nachricht vom 26.05.2017 09:14 (localtime):

The trace is from the pnaic after doing 'vale-ctl -a vale0:lagg0' (while
lagg0 can have various names, but I'm not using a vlan clone).

Might be that existing, but to my understanding uninvolved vlan clones
interfere here...
The lagg0 does have vlan clones (lots of) defined.
Unfortunately I can't take them out of the game for testing...

Does that picture match the trace?

thanks,
