From aae9e27f3b72ed58d6b87c8f511e7812601a93c5 Mon Sep 17 00:00:00 2001 From: Mika Westerberg Date: Sun, 19 Feb 2017 23:37:35 +0200 Subject: [PATCH] thunderbolt: Deactivate all paths before restarting them State of the connected devices and tunnel configuration is not known during resume. For example some paths may not be complete anymore if the user has unplugged the related devices. So instead of marking all paths as inactive we go ahead and deactivate them explicitly before we restart them.
