Subject: [PATCH net-next 0/2] mv88e6xxx: Disable ports to save power
Date: Wed, 1 May 2019 00:08:29 +0200 [thread overview]
Message-ID: <20190430220831.19505-1-andrew@lunn.ch> (raw)
Save some power by disabling ports. The first patch fully disables a
port when it is runtime disabled. The second disables any ports which
are not used at all.
Depending on configuration strapping, this can lower the temperature
of an idle switch a few degrees.
