If a neutron network MTU is too small, br-ex will be set to 1280 anyway, which might be problematic if the neutron mtu is smaller than that. we should have some validation in the installer to prevent this.
We need an MTU of 1380 at least, where 1280 is the minimum allowed for IPv6 + 100 for the OVN-Kubernetes encapsulation overhead.
