+==========================
+Link Power Managent Policy
+==========================
+
+This parameter allows the user to set the link (interface) power management.
+There are 3 possible options:
+
+=====================   =====================================================
+Value			Effect
+=====================   =====================================================
+min_power		Tell the controller to try to make the link use the
+			least possible power when possible.  This may
+			sacrifice some performance due to increased latency
+			when coming out of lower power states.
+
+max_performance		Generally, this means no power management.  Tell
+			the controller to have performance be a priority
+			over power management.
+
+medium_power		Tell the controller to enter a lower power state
+			when possible, but do not enter the lowest power
+			state, thus improving latency over min_power setting.
