In addition to basic sanity checks, tests add RSS contexts, n-tuple rule to direct traffic to them (based on dst port), and qstats to make sure traffic landed where we expected. v2 adds a test for removing contexts out of order. When testing bnxt - either the new test or running more tests after the overlap test makes the device act strangely. To the point where it may start giving out ntuple IDs of 0 for all rules :S Ed, could you try the tests with your device? $ export NETIF=eth0 REMOTE_... $ ./drivers/net/hw/rss_ctx.py KTAP version 1 1..8 ok 1 rss_ctx.test_rss_key_indir ok 2 rss_ctx.test_rss_context ok 3 rss_ctx.test_rss_context4 # Increasing queue count 44 -> 66 # Failed to create context 32, trying to test what we got ok 4 rss_ctx.test_rss_context32 # SKIP Tested only 31 contexts, wanted 32 ok 5 rss_ctx.test_rss_context_overlap ok 6 rss_ctx.test_rss_context_overlap2 # .. sprays traffic like a headless chicken .. not ok 7 rss_ctx.test_rss_context_out_of_order ok 8 rss_ctx.test_rss_context4_create_with_cfg # Totals: pass:6 fail:1 xfail:0 xpass:0 skip:1 error:0 Jakub Kicinski (4): selftests: drv-net: try to check if port is in use selftests: drv-net: add helper to wait for HW stats to sync selftests: drv-net: add ability to wait for at least N packets to load gen selftests: drv-net: rss_ctx: add tests for RSS configuration and contexts .../testing/selftests/drivers/net/hw/Makefile | 1 + .../selftests/drivers/net/hw/rss_ctx.py | 383 ++++++++++++++++++ .../selftests/drivers/net/lib/py/env.py | 20 +- .../selftests/drivers/net/lib/py/load.py | 37 +- tools/testing/selftests/net/lib/py/ksft.py | 5 + tools/testing/selftests/net/lib/py/utils.py | 26 +- 6 files changed, 457 insertions(+), 15 deletions(-) create mode 100755 tools/testing/selftests/drivers/net/hw/rss_ctx.py Reviewed-by: Willem de Bruijn
