From 4b4833acc63e9c8ea9d5897ee84b694f30b23882 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Alexis=20Lothor=C3=A9=20=28eBPF=20Foundation=29?= Date: Fri, 28 Nov 2025 23:27:18 +0100 Subject: [PATCH] selftests/bpf: rename test_tc_edt.bpf.c section to expose program type MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The test_tc_edt BPF program uses a custom section name, which works fine when manually loading it with tc, but prevents it from being loaded with libbpf. Update the program section name to "tc" to be able to manipulate it with a libbpf-based C test.
