Folks, we're hoping to declare the packet format frozen, so please
double-check we didn't do anything stupid.

Note that there's a good reason why we're using three new TLV types rather
than a sub-TLV within the existing TLVs -- it's for compatibility with
plain Babel routers.  The way we do it, existing routers will silently
ignore the whole new TLV, while with a sub-TLV, existing routers would
discard the unknown sub-TLV and hence mis-interpret the rest of the TLV.

Please see
