+Subject: [PATCH] device: add veth support
+
+The veth config code mostly handles the primary interface of a veth pair,
+the secondary interface is not explicitly referenced and will be found as
+an unrelated interface after the pair has been created.
+
+This doesn't only allow us to keep the veth code simple (and similar to
+existing device handlers), but will also avoid complicating handling
+unnecessarily in case the secondary interface is moved into another network
+namespace.
