7This parameter allows the user to set the link (interface) power management.
8There are 3 possible options:
9
10=====================   =====================================================
11Value			Effect
12=====================   =====================================================
13min_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.
17
18max_performance		Generally, this means no power management.  Tell
19			the controller to have performance be a priority
20			over power management.
21
22medium_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.
