Public bug reported:

when working with jumbo frames you can set MTU in nova.conf for the instaces' tap devices, and you can set it in neturon/plugins.ini for br-int. this allows you to work with jumbo frames inside a network.
However, if you want to work with jumbo frames across networks, there's no way to configure this on a router/l3-agent, and you have to manually set the mtu on the nics inside the namespaces
