Let's say I need to change the policy a few times before 1.5 Gbps are
reached and the speed is always lowered to 3.0 Gbps first.
I've never noticed any different trend, but I haven't observed this
problem enough. The policy is normally changed when I plug and unplug
my laptop, so not frequently enough to be a 100% sure.

I could do some tests though, all I need is to do is change the policy
a bunch of times.

There's connected an SSD. Let me know if you need more information than
those in the dmesg here below.

"setting max_performance" and "setting min_power" were added by me.
