Change MTU on GIF Interface

Unless I'm missing something, there seems to be no way to change the MTU on a 6in4 tunnel.

My tunnel broker allows the use of a higher MTUs which I would love to be able to take advantage of in the future.

you can change mtu via ifconfig on any interface.

I believe its the default value. We do not explicitly set it to 1280 if that is what you are referring to.
