When doing modprobe cls_u32 I always get the error message: unresolved symbol tcf_police_dump unresolved symbol tcf_police unresolved symbol tcf_police_destroy unresolved symbol unregister_tcf_proto_ops unresolved symbol register_tcf_proto_ops unresolved symbol tcf_police_locate insmod cls_u32 failed What did I forget to compile? btw none of the cls_ modules is loadable. Thx a lot in advance, André Weidemann.
