Vlan loses parent interface when changing LAGG mtu to jumbo frames
0%
Description
Hi,
Psense+ version: 22.01
When I try to add jumbo frames to lagg interface ( 9000 ) - main
When I change the main interface enabled with no ip address the vlans configured under the lagg instantly lose their parent device.
lagg1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 9000
description: LAGG1
ifconfig lagg1.115|grep vlan
groups: vlan
vlan: 0 vlanpcp: 0 parent interface: <none>
How am I suppose to enable jumbo frames on a aggregated link without losing vlan device links?
Also how to keep it persistent from the gui without doing hacks during bootup.

it appears with 22.05 too.
to workaround :
re-save the Lagg interface Interfaces>LAGGs
after resaving:
lagg0.100: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 9000
options=3<RXCSUM,TXCSUM>
ifconfig lagg0.100|grep vlan
groups: vlan
vlan: 100 vlanpcp: 0 parent interface: lagg0

Same behavior in 22.05, saving the (parent) interface with with IPv4/6 set to none and MTU 9000 kills connectivity on any VLANs on the LAGG. Reverting config and reboot/reroot restores connectivity. Config corrected, saving/applying interfaces and resetting states did not restore connectivity to sub-interfaces.
