selftests: net: py: read ip link info about remote dev

2025-11-21T02:19:29Z

We're already saving the info about the local dev in env.dev for the tests, save remote dev as well. This is more symmetric, env generally provides the same info for local and remote end. While at it make sure that we reliably get the detailed info about the local dev. nsim used to read the dev info without -d.

This fix solves this error, when calling kselftest with targets "drivers/net": File "tools/testing/selftests/net/lib/py/nsim.py", line 64, in __init__ if e.errno == errno.ENOSPC: NameError: name 'errno' is not defined The error was found by running tests manually with the command: make kselftest TARGETS="drivers/net" The module errno makes available standard error system symbols.

net: selftest: add test for netdev netlink queue-get API

2024-05-09T01:59:47Z

Add a selftest for netdev generic netlink. For now there is only a single test that exercises the `queue-get` API. The test works with netdevsim by default or with a real device by setting NETIF. Add a timeout param to cmd() since ethtool -L can take a long time on real devices.

selftests: net: support use of NetdevSimDev under "with" in python

2024-04-15T18:21:12Z

Using "with" on an entire driver test env is supported already, but it's also useful to use "with" on an individual nsim. Reviewed-by: Petr Machata Link: https://lore.kernel.org/r/20240412141436.828666-6-kuba@kernel.org Signed-off-by: Jakub Kicinski

selftests: drivers: add scaffolding for Netlink tests in Python

2024-04-08T10:40:41Z

Add drivers/net as a target for mixed-use tests. The setup is expected to work similarly to the forwarding tests. Since we only need one interface (unlike forwarding tests) read the target device name from NETIF. If not present we'll try to run the test against netdevsim.
