henrik, starting freebsd 4.8 and 5.0, you dont need a patch to support
wccp... it is already included inside /usr/src/sys/netinet/ip_gre.c

a sample code taken from ip_gre.c:

                case ETHERTYPE_IP: /* shouldn't need a schednetisr(), as */
                case WCCP_PROTOCOL_TYPE: /* we are in ip_input */
                        ifq = &ipintrq;
                        break;

i used freebsd 5.0 + wccp + ipfw without a problem...

fooler.
