From 34a79f63bbe49c888f95e75dd759685a238556b6 Mon Sep 17 00:00:00 2001 From: Vivien Didelot Date: Mon, 18 Jul 2016 20:45:38 -0400 Subject: net: dsa: support switchdev ageing time attr Add a new function for DSA drivers to handle the switchdev SWITCHDEV_ATTR_ID_BRIDGE_AGEING_TIME attribute. The ageing time is passed as milliseconds. Also because we can have multiple logical bridges on top of a physical switch and ageing time are switch-wide, call the driver function with the fastest ageing time in use on the chip instead of the requested one.
