7f0a8382 ("bpf, xdp: Maintain info on attached XDP BPF programs in net_device") inadvertently changed which XDP mode is assumed when no mode flags are specified explicitly. Previously, driver mode was preferred, if driver supported it. If not, generic SKB mode was chosen. That commit changed default to SKB mode always. This patch fixes the issue and restores the original logic. Fixes: 7f0a8382 ("bpf, xdp: Maintain info on attached XDP BPF programs in net_device") Reported-by:
