commit 5c8dffa7fb6c95a04a7b50c7d6e63c9a2729231b Author: Ihar Hrachyshka <[email protected]> Date: Tue Nov 29 22:24:29 2016 +0000 Update MTU on existing devices This patch makes OVS and Linuxbridge interface drivers to set MTU on plug() attempt if the device already exists. This helps when network MTU changes (which happens after some configuration file changes). This will allow to update MTU values on agent restart, without the need to bind all ports to new nodes, that would involve migrating agents. It will also help in case when you have no other nodes to migrate to (in single node mode). Both OVS and Linuxbridge interface drivers are updated. Other drivers (in-tree IVS as well as 3party drivers) will use the default set_mtu implementation, that only warns about the missing feature (once per process startup). DocImpact suggest to restart agents after MTU config changes instead of rewiring router/DHCP ports.

Without that, there is no way to apply new MTU for DHCP and router ports without migrating resources to other nodes. I suggest we apply MTU on conseqent plug() attempts, even if port exists.
