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