In Mitaka, you can now set global_physnet_mtu to the underlying NIC MTU
value, and then all devices managed by nova and neutron should adopt to
that, including considerations for tunneling overhead.

Title:
  can't set MTU size for router interface

Status in neutron:
  Confirmed

Bug description:
  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
