Not in mainline so far, so maybe we can fit your extensions
and my patches without the mobile extensions, that apparently
exceed the CB anyway, in there for now. Can I look at those
patches somewhere? BTW, other fields in the IP6CB seem to
store offsets in u16 fields, is this OK for nhoff too? I
thought with jumbo options I need to use a u32 field.
