Configure infrastructure MTU with global_physnet_mtu

Ihar Hrachyshka · Ihar Hrachyshka · commit f5d3bdb99fab · 2016-07-15T19:22:07.000+02:00
The network_device_mtu option will be removed from Neutron in Newton.
The global_physnet_mtu option was introduced in Mitaka. Before Mitaka,
Neutron did not have any multinode jobs that would require setting the
infrastructure MTU for inter-node connectivity.
