It is on by default because it the majority of cases its a benefit, you
found it to be a problem and turned it off, your problem is solved.

I admit, at one point I considered disabling it automatically for anything
under Gig speed, but a large community has used this driver with this
feature for over a year, no one has lobbied to have to disabled, so I
have not.

If there are others who think this would be a good idea, speak up, and
I will do so.
