selftests: drivers: add scaffolding for Netlink tests in Python 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.

net: Update threaded state in napi config in netif_set_threaded Commit 2677010e7793 ("Add support to set NAPI threaded for individual NAPI") added support to enable/disable threaded napi using netlink. This also extended the napi config save/restore functionality to set the napi threaded state. This breaks netdev reset for drivers that use napi threaded at device level and also use napi config save/restore on napi_disable/napi_enable. Basically on netdev with napi threaded enabled at device level, a napi_enable call will get stuck trying to stop the napi kthread. This is because the napi->config->threaded is set to disabled when threaded is enabled at device level. The issue can be reproduced on virtio-net device using qemu. To reproduce the issue run following, echo 1 > /sys/class/net/threaded ethtool -L eth0 combined 1 Update the threaded state in napi config in netif_set_threaded and add a new test that verifies this scenario.

This test exercises the init_netconsole() path and validates proper parsing of the netconsole= parameter format. The test: - Loads netconsole module with cmdline configuration instead of dynamic reconfiguration - Validates message transmission through the configured target - Adds helper functions for cmdline string generation and module validation This complements existing netconsole selftests by covering the module initialization code path that processes boot-time parameters. This test is useful to test issues like the one described in [1].

Basic CPU sysdata functionality - verifies that cpu=X is appended to messages 2. CPU sysdata with userdata - ensures CPU data works alongside userdata 3. Disabled CPU sysdata - confirms no CPU data is included when disabled The test uses taskset to control which CPU sends messages and verifies the reported CPU matches the one used. This helps ensure that netconsole accurately tracks and reports the originating CPU of messages.

selftests: net: add netpoll basic functionality test Add a basic selftest for the netpoll polling mechanism, specifically targeting the netpoll poll() side. The test creates a scenario where network transmission is running at maximum speed, and netpoll needs to poll the NIC. This is achieved by: 1. Configuring a single RX/TX queue to create contention 2. Generating background traffic to saturate the interface 3. Sending netconsole messages to trigger netpoll polling 4. Using dynamic netconsole targets via configfs 5. Delete and create new netconsole targets after some messages 6. Start a bpftrace in parallel to make sure netpoll_poll_dev() is called 7. If bpftrace exists and netpoll_poll_dev() was called, stop. The test validates a critical netpoll code path by monitoring traffic flow and ensuring netpoll_poll_dev() is called when the normal TX path is blocked. This addresses a gap in netpoll test coverage for a path that is tricky for the network stack.
