 Can you please add a printf to the ioctl code in src/sys/dev/ic/i82557.c
 line 221 (at least in -current, maybe slightly offset in netbsd-5) and
 see if it hits the fxp_init() in this block:
 
                 if (cmd != SIOCADDMULTI && cmd != SIOCDELMULTI)
                         ;
                 else if (ifp->if_flags & IFF_RUNNING) {
                         /*
                          * Multicast list has changed; set the
                          * hardware filter accordingly.
                          */
                         while (sc->sc_txpending) {
                                 sc->sc_flags |= FXPF_WANTINIT;
                                 tsleep(sc, PSOCK, "fxp_init", 0);
                         }
                         error = fxp_init(ifp);
                 }
                 break;
 
 ?
 
 
 Thanks,
