how is this feature related to data center compatibility level that it 
requires it to be 3.1?
I'd even say this feature is limited to host level of 3.1, not cluster 
level?

the only item which would be a DC level is changing MTU, since it should 
affect all hosts in the DC using that logical network.

as for MTU max value - I agree we need to check if there is a way to 
validate it across all hosts, but I'm pretty sure a config based 
validation for min/max mtu sizes is needed.
then a host could fail the change if the MTU isn't supported by it.

while MTU is relevant in this verb to setup networks, the change of the 
MTU itself as at logical network at DC level, so it needs a flow for 
handling a change across all hosts?
