Hm, joy. So that's a third way of negotiating the MTU, and this time
possibly even after the interface has been set up?

We haven't really understood how the X-CSTP-Base-MTU thing works yet, have
we? Or indeed how it can *ever* work reliably... which may explain why
there's now a new method :)

It might be worth trying to get this into 6.00; I'll take a look. Thanks.
