The series of patches are for doing basic tests of NIC driver. 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 <mohan.prasad@xxxxxxxxxxxxx> --- Changes in v4: - Type hints are added for arguments and return types. - Test values can be modified through command line. - Minor code improvements. - GenerateTraffic class extended for throughput test. - Protocol testcases separated. Changes in v3: Link to v3: https://patchwork.kernel.org/project/netdevbpf/cover/20241016215014.401476-1-mohan.prasad@xxxxxxxxxxxxx/ - 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: Link to v2: https://patchwork.kernel.org/project/netdevbpf/cover/20240917023525.2571082-1-mohan.prasad@xxxxxxxxxxxxx/ - 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.
