Subject: [PATCH 15/28] thunderbolt: Deactivate all paths before restarting them
Date: Tue, 29 Jan 2019 18:01:30 +0300 [thread overview]
Message-ID: <20190129150143.12681-16-mika.westerberg@linux.intel.com> (raw)
In-Reply-To: <20190129150143.12681-1-mika.westerberg@linux.intel.com>
We can't be sure the paths are actually properly deactivated when a
tunnel is restarted after resume. So instead of marking all paths as
inactive we go ahead and deactivate them explicitly.
