Not sure to understand exactly how this relates to the issue that I'm
experiencing: besides that rfkill in my case is not an issue (wifi was
on and rfkill off), this has to be read "it depends on the driver"? in
this case I guess we have a problem: how can wpa (thus the end user)
be sure to act correctly to connect to wifi? basically from what i
read no one in the stack is taking care of this...

Sorry if I made bad mistakes, of course.
