The per-CPU flush lists, which are accessed from within the NAPI callback (xdp_do_flush() for instance), are per-CPU. There are subject to the same problem as struct bpf_redirect_info. Add the per-CPU lists cpu_map_flush_list, dev_map_flush_list and xskmap_map_flush_list to struct bpf_net_context. Add wrappers for the access. The lists initialized on first usage (similar to bpf_net_ctx_get_ri()).
