      Just a note for those with an MTU manually set on an interface. When upgrading to 2.3, your interface may lose the MTU and it will need to be manually reset.

      In my case, I have a parent LAGG and several child VLAN interfaces. The LAGG was reporting the MTU correctly in Status - Interfaces, but the child VLAN interfaces were not inheriting it and stuck in an 'INIT?' state. After a little research I noticed that although the parent LAGG was reporting it's MTU correctly, the MTU field under the interface setting was blank. After manually resetting it (to 9000 in my case) and rebooting the box, the child VLAN interfaces inherited the MTU correctly.
