From b2f2af21e37f6d12bd735c27da8942331aa9b3d7 Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Wed, 24 Sep 2014 17:05:18 -0700 Subject: net: dsa: allow enabling and disable switch ports Whenever a per-port network device is used/unused, invoke the switch driver port_enable/port_disable callbacks to allow saving as much power as possible by disabling unused parts of the switch (RX/TX logic, memory arrays, PHYs...). We supply a PHY device argument to make sure the switch driver can act on the PHY device if needed (like putting/taking the PHY out of deep low power mode).
