This should mention what the reference is - so 100% is 100% of what (it
would be the 802.3 specified 100BASE-TX level, but it should make that
clear.)

I'm having a hard time trying to find its specification in 802.3, so
maybe a reference to where it can be found would be useful, otherwise
it's unclear what one gets for "100%".
