From 647b502e3d5456f5c240b1587112b163c69732e9 Mon Sep 17 00:00:00 2001 From: Yonghong Song Date: Tue, 23 Jun 2020 16:08:17 -0700 Subject: selftests/bpf: Refactor some net macros to bpf_tracing_net.h Refactor bpf_iter_ipv6_route.c and bpf_iter_netlink.c so net macros, originally from various include/linux header files, are moved to a new header file bpf_tracing_net.h. The goal is to improve reuse so networking tracing programs do not need to copy these macros every time they use them.
