From bd8e1afe6436558de3a7b25eaef34b69d98e5719 Mon Sep 17 00:00:00 2001 From: Paolo Abeni Date: Wed, 7 Nov 2018 12:38:35 +0100 Subject: selftests: add dummy xdp test helper 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: Paolo Abeni Signed-off-by: David S.
