0004 Link Power Managent Policy
0005 ==========================
0006 
0007 This parameter allows the user to set the link (interface) power management.
0008 There are 3 possible options:
0009 
0010 =====================   =====================================================
0011 Value                   Effect
0012 =====================   =====================================================
0013 min_power               Tell the controller to try to make the link use the
0014                         least possible power when possible.  This may
0015                         sacrifice some performance due to increased latency
0016                         when coming out of lower power states.
0017 
0018 max_performance         Generally, this means no power management.  Tell
0019                         the controller to have performance be a priority
0020                         over power management.
0021 
0022 medium_power            Tell the controller to enter a lower power state
0023                         when possible, but do not enter the lowest power
0024                         state, thus improving latency over min_power setting.
