There is currently no difference in how ``Supported`` and ``Maintained`` +drivers are treated upstream. + +The exact rules a driver must follow to acquire the ``Supported`` status: + +1. Must run all tests under ``drivers/net`` and ``drivers/net/hw`` targets + of Linux selftests. Running and reporting private / internal tests is + also welcome, but upstream tests are a must. + +2. The minimum run frequency is once every 12 hours. Must test the + designated branch from the selected branch feed. Note that branches + are auto-constructed and exposed to intentional malicious patch posting, + so the test systems must be isolated. + +3. Drivers supporting multiple generations of devices must test at + least one device from each generation. A testbed manifest (exact + format TBD) should describe the device models tested. + +4. The tests must run reliably, if multiple branches are skipped or tests + are failing due to execution environment problems the ``Supported`` + status will be withdrawn. + +5. Test failures due to bugs either in the driver or the test itself, + or lack of support for the feature the test is targgeting are + *not* a basis for losing the ``Supported`` status. + +netdev CI will maintain an official page of supported devices, listing their +recent test results. + +The driver maintainer may arrange for someone else to run the test, +there is no requirement for the person listed as maintainer (or their +employer) to be responsible for running the tests. Collaboration between +vendors, hosting GH CI, other repos under linux-netdev, etc. is most welcome. + +See https://github.com/linux-netdev/nipa/wiki for more information about +netdev CI.
