You might get warnings about CamelCase, but i suggest keep_link_10M,
keep_link_100M and keep_link_1000M. These are megabits, not millibits.

What does keep mean in this context?

Yes, i already said this needs handling differently. The 2Hz, 4Hz and
8Hz naturally fit the delay_on, delay_of sysfs attributes.
