The old mtu default in containerization was 1280 to account for some alpine/musl images that have issues with 1500. This changed in the last couple tags to be modifiable, but the new default is the standard 1500. Ideally we eventually allow supplying the mtu to be used when you create a network (or possibly a container creation setting), but for now just default in here back to what CZ used to use.
