  4. ==========================
  5. This parameter allows the user to set the link (interface) power management.
  6. There are 3 possible options:
  7. ===================== =====================================================
  8. Value Effect
  9. ===================== =====================================================
  10. min_power Tell the controller to try to make the link use the
  11. least possible power when possible. This may
  12. sacrifice some performance due to increased latency
  13. when coming out of lower power states.
  14. max_performance Generally, this means no power management. Tell
  15. the controller to have performance be a priority
  16. over power management.
  17. medium_power Tell the controller to enter a lower power state
  18. when possible, but do not enter the lowest power
  19. state, thus improving latency over min_power setting.
