This patch series introduces enhancements to xsk selftests, focusing on
dynamic batch size configurations and robust traffic validation.
v1->v2:
- Correctly bind UMEM queue sizes to TX and RX queues for standard
operational alignment.
- Set cfg.rx_size directly from umem->fill_size when umem->fill_size is
true, ensuring alignment with test specifications.
v2->v3:
- Update commit messages and cover letter for clarity and precision in
documentation.
Patch series summary:
Patch 1/2: Robust traffic validation post-ring size adjustment
- Fixed the flow in HW_SW_MIN_RING_SIZE and HW_SW_MAX_RING_SIZE test cases
to validate Tx/Rx traffic by checking the return value of
set_ring_size(), preventing premature test termination.
Patch 2/2: Dynamic batch size configuration
- Overcomes the 2K batch size limit by introducing dynamic adjustments for
fill_size and comp_size.
- Update HW_SW_MAX_RING_SIZE test case that evaluates the maximum ring
sizes for AF_XDP, ensuring its reliability under maximum ring utilization.
Ensure the xsk selftests patches improve overall reliability and
efficiency, allowing the system to handle larger batch sizes and
effectively validate traffic after configuration changes.
