I checked on the neutron IRC and MTU cannot be set by API/GUI/CLI. MTU
is calculated by neutron as per your config options global_physnet_mtu
and such, but it cant be set. There is a separate page in user guide for
MTU in newton http://docs.openstack.org/draft/networking-guide/config-
mtu.html

Via neutron net-update or REST API its not possible,cause I checked the
parameters and it didnt have MTU. Only neutron ipsec-site-connection-
update is the cli I could see MTU as a parameter.

A GET can let MTU be returned in network payload, assuming your plugin
supports net-mtu API extension. POST(edit) will not work.

It was suggested, we could in theory allow to request MTUs that are
lower than plugin calculated, that would be a feature request but only
if there is valid usecase around to lower your MTU.

I am cancelling this defect based on this discussion

Title:
  MTU specified during neutron network create is not honored, always set
  to 1500

Status in neutron:
  Invalid

Bug description:
  When I try to create a new neutron network with MTU say 1000, it is
  getting overwritten with a value of 1500.

  Is MTU not settable per neutron network?
