selftests: drv-net: update remaining Python init files

selftests: drv-net: make linters happy with our imports

2025-10-07T10:12:44+00:00

Linters are still not very happy with our __init__ files, which was pointed out in recent review (see Link). We have previously started importing things one by one to make linters happy with the test files (which import from __init__). But __init__ file itself still makes linters unhappy. To clean it up I believe we must completely remove the wildcard imports, and assign the imported modules to __all__. hds.py needs to be fixed because it seems to be importing the Python standard random from lib.net. We can't use ksft_pr() / ktap_result() in case importing from net.lib fails. Linters complain that those helpers themselves may not have been imported.

selftests: drv-net: wait for carrier

2025-08-15T00:44:46+00:00

On fast machines the tests run in quick succession so even when tests clean up after themselves the carrier may need some time to come back. Specifically in NIPA when ping.py runs right after netpoll_basic.py the first ping command fails. Since the context manager callbacks are now common NetDrvEpEnv gets an ip link up call as well.

selftests: drv-net: Make command requirements explicit

2025-07-25T01:52:00+00:00

Make require_cmd() calls explicit about whether commands are needed locally, remotely, or both. Since require_cmd() defaults to local=True, tests should explicitly set local=False when commands are only needed remotely. - socat: Set local=False since it's only needed on remote hosts. - iperf3: Use single call with both local=True and remote=True since it's needed on both hosts. This avoids unnecessary test failures when commands are missing locally but available remotely where actually needed, and consolidates a duplicate require_cmd() call into single call that checks both hosts.

selftests: drv-net: Fix remote command checking in require_cmd()

2025-07-25T01:52:00+00:00

The require_cmd() method was checking for command availability locally even when remote=True was specified, due to a missing host parameter. Fix by passing host=self.remote when checking remote command availability, ensuring commands are verified on the correct host.

selftests: drv-net: wait for iperf client to stop sending

2025-07-24T01:52:12+00:00

A few packets may still be sent out during the termination of iperf processes. These late packets cause failures in rss_ctx.py when they arrive on queues expected to be empty. Example failure observed: Check failed 2 != 0 traffic on inactive queues (context 1): [0, 0, 1, 1, 386385, 397196, 0, 0, 0, 0, ...] Check failed 4 != 0 traffic on inactive queues (context 2): [0, 0, 0, 0, 2, 2, 247152, 253013, 0, 0, ...] Check failed 2 != 0 traffic on inactive queues (context 3): [0, 0, 0, 0, 0, 0, 1, 1, 282434, 283070, ...] To avoid such failures, wait until all client sockets for the requested port are either closed or in the TIME_WAIT state.
