SPDX-License-Identifier: GPL-2.0 + +Running driver tests +==================== + +Networking driver tests are executed within kselftest framework like any +other tests. They support testing both real device drivers and emulated / +software drivers (latter mostly to test the core parts of the stack). + +SW mode +~~~~~~~ + +By default, when no extra parameters are set or exported, tests execute +against software drivers such as netdevsim. No extra preparation is required +the software devices are created and destroyed as part of the test. +In this mode the tests are indistinguishable from other selftests and +(for example) can be run under ``virtme-ng`` like the core networking selftests. + +HW mode +~~~~~~~ + +Executing tests against a real device requires external preparation. +The netdevice against which tests will be run must exist, be running +(in UP state) and be configured with an IP address. + +Refer to list of :ref:`Variables` later in this file to set up running +the tests against a real device. + +Both modes required +~~~~~~~~~~~~~~~~~~~ + +All tests in drivers/net must support running both against a software device +and a real device.
