An error will be output when I specify MTU bigger than 1442 with Geneve.

Value of MTU should be...

• 1450: for Linux Bridge
• 1442: for Geneve If we will build an OpenStack environment on virtual machines like KVM, we should specify less than them.

It has been closed because it should be solved in configurations.
