From 47844ecb8cec2916abaad9c1d1b801f49ed6265d Mon Sep 17 00:00:00 2001 From: Mika Westerberg Date: Wed, 7 Oct 2020 18:19:28 +0300 Subject: thunderbolt: Create XDomain devices for loops back to the host It is perfectly possible to have loops back from the routers to the host, or even from one host port to another. Instead of ignoring these, we create XDomain devices for each. This allows creating services such as DMA traffic test that is used in manufacturing for example.
