otherwise it times out when sending too much data; so leaving it as a separate follow up v2: - don't remove validation (Mina) - keep 5-tuple flow steering but use it only when -c is provided (Mina) - remove separate flag for probing (Mina) - move ncdevmem under drivers/net/hw, not drivers/net (Jakub) Cc: Mina Almasry Stanislav Fomichev (12): selftests: ncdevmem: Redirect all non-payload output to stderr selftests: ncdevmem: Separate out dmabuf provider selftests: ncdevmem: Unify error handling selftests: ncdevmem: Make client_ip optional selftests: ncdevmem: Remove default arguments selftests: ncdevmem: Switch to AF_INET6 selftests: ncdevmem: Properly reset flow steering selftests: ncdevmem: Use YNL to enable TCP header split selftests: ncdevmem: Remove hard-coded queue numbers selftests: ncdevmem: Run selftest when none of the -s or -c has been provided selftests: ncdevmem: Move ncdevmem under drivers/net/hw selftests: ncdevmem: Add automated test .../selftests/drivers/net/hw/.gitignore | 1 + .../testing/selftests/drivers/net/hw/Makefile | 9 + .../selftests/drivers/net/hw/devmem.py | 45 + .../selftests/drivers/net/hw/ncdevmem.c | 773 ++++++++++++++++++ tools/testing/selftests/net/.gitignore | 1 - tools/testing/selftests/net/Makefile | 8 - tools/testing/selftests/net/ncdevmem.c | 570 ------------- 7 files changed, 828 insertions(+), 579 deletions(-) create mode 100644 tools/testing/selftests/drivers/net/hw/.gitignore create mode 100755 tools/testing/selftests/drivers/net/hw/devmem.py create mode 100644 tools/testing/selftests/drivers/net/hw/ncdevmem.c delete mode 100644 tools/testing/selftests/net/ncdevmem.c
