selftests: add dummy xdp test helper (bd8e1afe) · Commits · 戴 / test

This trivial XDP program does nothing, but will be used by the next patch to test the GRO path in a net namespace, leveraging the veth XDP implementation. It's added here, despite its 'net' usage, to avoid the duplication of the llc-related makefile boilerplate. rfc v3 -> v1: - move the helper implementation into the bpf directory, don't touch udpgso_bench_rx rfc v2 -> rfc v3: - move 'x' option handling here Signed-off-by:
