I try to look into if_vlan code and if I understand correct it try to set
MAC to parent adapter and read parent adapter MAC change.

But it must add/remove MAC addr to/from H/W MAC filter, not change only one.
It done for multicast join/leave, but not done for if_vlan and probably some other cases.
