2024-05-09selftests/bpf: Remove bpf_tracing_net.h usages from two networking testsMartin KaFai Lau
This patch removes the bpf_tracing_net.h usage from the networking tests, fib_lookup and test_lwt_redirect. Instead of using the (copied) macro TC_ACT_SHOT and ETH_HLEN from bpf_tracing_net.h, they can directly use the ones defined in the network header files under linux/.
