--- Comment #44 from Marek Zarychta <zarychtam@plan-b.pwste.edu.pl> ---
The bug was introduced somewhere in 13.0-CURRENT (see bug 260260). 
Since early stable/13 I am working around this by setting MTU to 9004 on faulty
igb/em(4) interfaces, 9004 is inherited by lagg(4), but for children, vlan(4)
MTU 9000 is assigned.
