Hi Edy and Fernando,
This is what I found to workaround the VLAN MTU bug:
1. Include vlan interface in desired state if base-iface changed
its MTUs.
2. Place vlan interface __after__ other interface when activation
To test whether step 2 works, I created patch:

It works well when I include both vlan and base-iface in the same
yml file with base-iface changed its MTU.
Hope this helps.
