selftests: drv-net: pp_alloc_fail: lower traffic expectations

2025-10-09T09:10:02+00:00

Lower the expected level of traffic in the pp_alloc_fail test
and calculate failure counter thresholds based on the traffic
rather than using a fixed constant.

We only have "QEMU HW" in NIPA right now, and the test (due to
debug dependencies) only works on debug kernels in the first place.
We need some place for it to pass otherwise it seems to be bit
rotting. So lower the traffic threshold so that it passes on QEMU
and with a debug kernel...

selftests: drv-net: fix linter warnings in pp_alloc_fail

2025-10-09T09:10:02+00:00

Fix linter warnings, it's a bit hard to check for new ones otherwise.

  W0311: Bad indentation. Found 16 spaces, expected 12 (bad-indentation)
  C0114: Missing module docstring (missing-module-docstring)

selftests: drv-net: xdp: add test for interface level qstats

2025-10-09T09:10:02+00:00

Send a non-trivial number of packets and make sure that they
are counted correctly in qstats. Per qstats specification
XDP is the first layer of the stack so we should see Rx and Tx
counters go up for packets which went thru XDP.

selftests: drv-net: xdp: rename netnl to ethnl

2025-10-09T09:10:02+00:00

Test uses "netnl" for the ethtool family which is quite confusing
(one would expect netdev family would use this name).

No functional changes.

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: net: unify the Makefile formats

2025-10-06T20:14:06+00:00

We get a significant number of conflicts between net and net-next
because of selftests Makefile changes. People tend to append new
test cases at the end of the Makefile when there's no clear sort
order. Sort all networking selftests Makefiles, use the following
format:

 VAR_NAME := \
	 entry1 \
	 entry2 \
	 entry3 \
 # end of VAR_NAME

Some Makefiles are already pretty close to this.
