This patch series add tests to validate XDP native support for PASS, DROP, ABORT, and TX actions, as well as headroom and tailroom adjustment. For adjustment tests, validate support for both the extension and shrinking cases across various packet sizes and offset values.
The pass criteria for head/tail adjustment tests require that at-least one adjustment value works for at-least one packet size. This ensure that the variability in maximum supported head/tail adjustment offset across different drivers is being incorporated.
The results reported in this series are based on fbnic. However, the series is tested against multiple other drivers including netdevism.
Note: The XDP support for fbnic will be added later. --- Change-log: V4: - Support XDP handling for netdevsim - Fix pylint warning with P4 - Update commit message for P2,P3 to show pass/fail summary V3: https://lore.kernel.org/netdev/20250712002648.2385849-1-mohsin.bashr@gmail.c...
