Subject: [PATCH 17/17] thunderbolt: Add KUnit tests for tunneling
Date: Mon, 15 Jun 2020 17:26:45 +0300 [thread overview]
Message-ID: <20200615142645.56209-18-mika.westerberg@linux.intel.com> (raw)
In-Reply-To: <20200615142645.56209-1-mika.westerberg@linux.intel.com>
We can test some parts of tunneling, like path allocation without access
to test hardware so add KUnit tests for PCIe, DP and USB3 tunneling.
