Add support for running our existing GRO test against HW GRO and LRO implementation. The first 3 patches are just ksft lib nice-to-haves, and patch 4 cleans up the existing gro Python.
Patches 5 and 6 are of most practical interest. The support reconfiguring the NIC to disable SW GRO and enable HW GRO and LRO. Additionally last patch breaks up the existing GRO cases to track HW compliance at finer granularity. v2: - fix restoring all features - apply the generic XDP hack selectively (print a msg when it happens) - a lot of small tweaks and 4 extra patches v1: https://lore.kernel.org/[email protected] Jakub Kicinski (6): selftests: net: py: teach ksft_pr() multi-line safety selftests: net: py: teach cmd() how to print itself selftests: drv-net: gro: use cmd print selftests: drv-net: gro: improve feature config selftests: drv-net: gro: run the test against HW GRO and LRO selftests: drv-net: gro: break out all individual test cases tools/testing/selftests/drivers/net/gro.c | 399 +++++++++++--------- tools/testing/selftests/drivers/net/gro.py | 158 ++++++-- tools/testing/selftests/net/lib/py/ksft.py | 29 +- tools/testing/selftests/net/lib/py/utils.py | 23 ++ 4 files changed, 406 insertions(+), 203 deletions(-) -- 2.52.0
