selftests: drv-net: convert so_txtime to drv-netIn preparation for extending to pacing hardware offload, convert theso_txtime.sh test to a drv-net test that can be run against netdevsimand real hardware.Also update so_txtime.c to not exit on first failure, but run tocompletion and report exit code there. This helps with debuggingunexpected results, especially when processing multiple packets,as happens in the "reverse_order" testcase.Signed-off-by: Willem de Bruijn ----v6 -> v7- update test to use new argument expect_fail- v6 received Reviewed-by, but dropped due to above (minor) changev5 -> v6- fix order in tools/testing/selftests/drivers/net/configv4 -> v5- move qdisc setup/restore into each test- add tc to utils.py (separate patch)- test expected failure (separate patch)- fix pylint- convert fail to pass for timing errors if KSFT_MACHINE_SLOW (cmd does not special case KSFT_SKIP process returncode yet)Responses to sashiko review- The test converts per packet failure to errors, to continue testing other packets, but other error() cases are not in scope.- The test starts sender and receiver at an absolute future time, like the original test.

net: Update threaded state in napi config in netif_set_threadedCommit 2677010e7793 ("Add support to set NAPI threaded for individualNAPI") added support to enable/disable threaded napi using netlink. Thisalso extended the napi config save/restore functionality to set the napithreaded state. This breaks netdev reset for drivers that use napithreaded at device level and also use napi config save/restore onnapi_disable/napi_enable. Basically on netdev with napi threaded enabledat device level, a napi_enable call will get stuck trying to stop thenapi kthread. This is because the napi->config->threaded is set todisabled when threaded is enabled at device level.The issue can be reproduced on virtio-net device using qemu.

selftests: net: add netpoll basic functionality testAdd a basic selftest for the netpoll polling mechanism, specificallytargeting the netpoll poll() side.The test creates a scenario where network transmission is running atmaximum 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 trafficflow and ensuring netpoll_poll_dev() is called when the normal TX pathis blocked.This addresses a gap in netpoll test coverage for a path that istricky for the network stack.Signed-off-by: Breno Leitao Reviewed-by: Willem de Bruijn Link: https://patch.msgid.link/20250714-netpoll_test-v7-3-c0220cfaa63e@debian.orgSigned-off-by: Jakub Kicinski List of files: /linux/tools/testing/selftests/drivers/net/Makefile
