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?

LED is turned on but doesn't blink. Hint for a better name?

This is very strange. Is option_blink_2hz a trigger on itself? Or just
an option for another trigger? It seems that it is an option, so that I
can set something like
  blink_tx,option_blink_2hz
and the LED will blink on tx activity with frequency 2 Hz... If that is
so, I think you are misnaming your macros or something, since you are
defining option_blink_2hz as a trigger with
 DEFINE_OFFLOAD_TRIGGER

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

You are totally right. I tought the blink control was something specific
that only some PHY had, but considering we have more than 1 that
supports a variant of it, I can see how it should be handled separately.
I assume even more have this kind of customizzation.
