From cc7e3f63d7299dd1119be39aa187b867d6f8aa17 Mon Sep 17 00:00:00 2001 From: Hangbin Liu Date: Fri, 3 Jan 2020 15:41:24 +0800 Subject: selftests: loopback.sh: skip this test if the driver does not support The loopback feature is only supported on a few drivers like broadcom, mellanox, etc. The default veth driver has not supported it yet. To avoid returning failed and making the runner feel confused, let's just skip the test on drivers that not support loopback.
