last week I got stuck in converting p4 code to .o bpf code, finally with lucky I solve it under the help of this link Invalid key type for BPF_MAP_TYPE_ARRAY. P4 programm based on ebpf_model.p4 template, now I get new issues, according to the instruction on p4c-epbf, use tc to load bpf code to kernel, but the version problem occurs, how can I solve it?
