commit a984f9554cdcbe93c840a1d8f5c04302e9331e79 Author: Ihar Hrachyshka <[email protected]> Date: Sat Jul 2 17:30:21 2016 +0200 Calculate MTU on every network fetch instead of on create Today, existing networks may not reflect MTU configured for neutron-server, if they were created when neutron-server was using different MTU setup for its infrastructure, or when it was using bad default values for network MTUs (specifically, before Mitaka, all networks were getting MTU = 0 by default, disabling both advertisement and data path MTU size enforcement). This patch stops persisting MTU in the database on network create and instead calculate it on every network resource fetch. DocImpact Now changes to MTU configuration options immediately affect existing network MTUs, not just new networks. UpgradeImpact Existing networks with invalid MTU persisted in database may change their MTU values to reflect configuration.

Engineering Team, which is subscribed to neutron. https://bugs.launchpad.net/bugs/1556182 Title: Migrate networks with MTU = 0 to a more reasonable value (1500?) Status in neutron: Fix Released Bug description: In Mitaka, new networks are now created with default 1500 mtu (minus tunneling overhead). But for old networks, mtu value is left intact, meaning they are still affected by MTU mismatch issues. We should migrate those resources to use a saner value for the attribute.
