Test comprises checks for auto-negotiation, speed, duplex state and throughput between local NIC and partner. Tools such as ethtool, iperf3 are used. Signed-off-by: Mohan Prasad J --- Changes in v3: - LinkConfig class is included in the hw library. This contains generic APIs for doing link layer operations. - Auto-negotiation checks involve changing the auto-neg state both in local and partner NIC. - Link layer test and performance test are separated to different selftest files. - Resetting of NIC driver done after test completion. Changes in v2: - Changed the hardcoded implementation of speed, duplex states, throughput to generic values, in order to support all type of NIC drivers. - Test executes based on the supported link modes between local NIC driver and partner. - Instead of lan743x directory, selftest file is now relocated to /selftests/drivers/net/hw. --- Mohan Prasad J (3): selftests: nic_link_layer: Add link layer selftest for NIC driver selftests: nic_link_layer: Add selftest case for speed and duplex states selftests: nic_performance: Add selftest for performance of NIC driver .../testing/selftests/drivers/net/hw/Makefile | 2 + .../drivers/net/hw/lib/py/__init__.py | 1 + .../drivers/net/hw/lib/py/linkconfig.py | 220 ++++++++++++++++++ .../drivers/net/hw/nic_link_layer.py | 105 +++++++++ .../drivers/net/hw/nic_performance.py | 121 ++++++++++ 5 files changed, 449 insertions(+) create mode 100644 tools/testing/selftests/drivers/net/hw/lib/py/linkconfig.py create mode 100644 tools/testing/selftests/drivers/net/hw/nic_link_layer.py create mode 100644 tools/testing/selftests/drivers/net/hw/nic_performance.py
