+
+                max_performance: Generally, this means no power management.

+                management.
+
+                medium_power: Tell the controller to enter a lower power state
+                when possible, but do not enter the lowest power state, thus

+There are some helpers to make this easier:

+

 This also affects drivers with the NETIF_F_FRAGLIST & NETIF_F_GSO_SCTP bits
 set. Note also that NETIF_F_GSO_SCTP is included in NETIF_F_GSO_SOFTWARE.

-          Enabling this option will attempt to work around some (but not all)
