--- Comment #2 from Rumen Palov <rpalov@e-card.bg> ---
Hello all,

the reason for not receiving traffic in FreeBSD 13.0 / 13.1 is the present =
vlan
devices in cloned_interfaces pragma in /etc/rc.conf.=20

When we remove the vlans from cloned_interfaces they are working properly.

To be more clear, when we have configuration like this, after update from
FreeBSD 12 to FreeBSD 13, vlans stop working:=20

cloned_interfaces=3D"lagg0 vlan100"
vlans_lagg0=3D"vlan100"
..........
create_args_vlan100=3D"vlan 100 vlandev lagg0"
ifconfig_vlan100=3D"inet 192.168.0.1/24"

When we remove the vlan100 from cloned_interfaces, vlans start working.

Until FreeBSD 13 they are working even present in cloned_interfaces.

What change is affecting that behavior ?
