--- Comment #2 from Praveen <praveenchoudary.gokina at emulex.com> ---
In Linux, when we change parent interface mtu, it will automatically update
vlan mtu.

We can either make it similar to Linux or handle as you said 

"give a warning or prevent the parent interface MTU from being reduced smaller
than any of the VLAN MTU (or conversely increasing the VLAN MTU above that of
the parent)".
