selftests: drv-net: Bring back tool() to driver inits

2026-01-17T15:35:28Z

[ Upstream commit 353cfc0ef3f34ef7fe313ae38dac37f2454a7cf5 ] The pp_alloc_fail.py test (which doesn't run in NIPA CI?) uses tool, add back the import.

selftests: drv-net: Add test for devlink-rate traffic class bandwidth distribution

2025-07-02T22:39:06Z

This test suite validates the functionality of the devlink-rate API for traffic class (TC) bandwidth allocation. It ensures that bandwidth can be distributed between different traffic classes as configured, and verifies that explicit TC-to-queue mapping is required for the allocation to be effective. The first test (test_no_tc_mapping_bandwidth) is marked as expected failure on mlx5, since the hardware automatically enforces traffic class separation by dynamically moving queues to the correct TC scheduler, even without explicit TC-to-queue mapping configuration. Test output on mlx5: 1..2 # Created VF interface: eth5 # Created VLAN eth5.101 on eth5 with tc 3 and IP 198.51.100.2 # Created VLAN eth5.102 on eth5 with tc 4 and IP 198.51.100.10 # Set representor eth4 up and added to bridge # Bandwidth check results without TC mapping: # TC 3: 0.19 Gbits/sec # TC 4: 0.76 Gbits/sec # Total bandwidth: 0.95 Gbits/sec # TC 3 percentage: 20.0% # TC 4 percentage: 80.0% ok 1 devlink_rate_tc_bw.test_no_tc_mapping_bandwidth # XFAIL Bandwidth matched 80/20 split without TC mapping # Created VF interface: eth5 # Created VLAN eth5.101 on eth5 with tc 3 and IP 198.51.100.2 # Created VLAN eth5.102 on eth5 with tc 4 and IP 198.51.100.10 # Set representor eth4 up and added to bridge # Bandwidth check results with TC mapping: # TC 3: 0.21 Gbits/sec # TC 4: 0.78 Gbits/sec # Total bandwidth: 0.98 Gbits/sec # TC 3 percentage: 21.1% # TC 4 percentage: 78.9% # Bandwidth is distributed as 80/20 with TC mapping ok 2 devlink_rate_tc_bw.test_tc_mapping_bandwidth # Totals: pass:1 fail:0 xfail:1 xpass:0 skip:0 error:0 Signed-off-by: Carolina Jubran Reviewed-by: Cosmin Ratiu Reviewed-by: Nimrod Oren Signed-off-by: Mark Bloch Link: https://patch.msgid.link/20250629142138.361537-9-mbloch@nvidia.com Signed-off-by: Jakub Kicinski

selftests: drv-net: import things in lib one by one

2025-06-23T19:55:20Z

pylint doesn't understand our path hacks, and it generates a lot of warnings for driver tests. Import what we use one by one, this is hopefully not too tedious and it makes pylint happy. Link: https://patch.msgid.link/20250621171944.2619249-9-kuba@kernel.org Signed-off-by: Jakub Kicinski

selftests: net-drv: remove the nic_performance and nic_link_layer tests

Revert fbbf93556f0c ("selftests: nic_performance: Add selftest for performance of NIC driver") Revert c087dc54394b ("selftests: nic_link_layer: Add selftest case for speed and duplex states") Revert 6116075e18f7 ("selftests: nic_link_layer: Add link layer selftest for NIC driver") These tests don't clean up after themselves, don't use the disruptive annotations, don't get included in make install etc. etc. The tests were added before we have any "HW" runner, so the issues were missed. Our CI doesn't have any way of excluding broken tests, remove these for now to stop the random pollution of results due to broken env. We can always add them back once / if fixed.
