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.
