if_index in struct ifnet broken in recent CURRENT

  Hmm, some more information: actually if_index is broken
not only in in mbuf packet headers.

This code with different addresses:

        bzero((caddr_t)&ro, sizeof(ro));
        sin = (struct sockaddr_in *)&ro.ro_dst;
        sin->sin_len = sizeof(*sin);
        sin->sin_family = AF_INET;
        sin->sin_addr = \\some address\\;
        rtalloc_ign(&ro, RTF_CLONING);
        if (ro.ro_rt != NULL) {
                struct rtentry *rt = ro.ro_rt;

                printf("rt idx %d, name %s\n",
                        rt->rt_ifp->if_index,
                        rt->rt_ifp->if_xname);

produces 

rt idx 0, name fxp0
rt idx 0, name lo0
