This parameter allows the user to set the link (interface) power management.

There are 3 possible options:

Value                   Effect

----------------------------------------------------------------------------

min_power               Tell the controller to try to make the link use the

                        least possible power when possible.  This may

                        sacrifice some performance due to increased latency

                        when coming out of lower power states.

max_performance         Generally, this means no power management.  Tell

                        the controller to have performance be a priority

                        over power management.

medium_power            Tell the controller to enter a lower power state

                        when possible, but do not enter the lowest power

                        state, thus improving latency over min_power setting.
