Currently, "none" completely disables the link layer adjustments,
"ethernet" enables them, but will only use the overhead (unless you specify an
tcMPU, but that is truly exotic).

On the one hand I agree, but the two options are called "ATM" (well for
tc "adsl" is a valid alias for ATM) and "ethernet" if you pass them to tc (what
we do), and I would really hate it to hide this under fancy names. I see no
chance of renaming those options in tc, so we are sort of stuck with them and
adding another layer of indirection seems too opaque to me. This is why I put
some explanation behind the option names in the list box…
Best
Sebastian
