I found ipfw_report(NULL, ..) is called at this point.

----- ip_fw.c:1305
                if (fw_verbose)
                        ipfw_report(NULL, ip, rif, oif);
                goto dropit;


After some debug, PULLUP_TO() in case IPPROTO_UDP.  Is reason for this
failing of m_pullup()?

----- ip_fw.c:1001
            case IPPROTO_UDP :
                PULLUP_TO(hlen + sizeof(struct udphdr));
                udp =(struct udphdr *)((u_int32_t *)ip + ip->ip_hl);
                dst_port = udp->uh_dport ;
                src_port = udp->uh_sport ;
