    struct ifnet *cyg_snmp_get_if(int if_num) {
      int index = 0;
      struct ifnet *ifp;
      do {
        while(0 == ifnet_addrs[index])
        ifp = ifnet_addrs[index]->ifa_ifp;
      } while (if_num);
      return ifp;

If the above code is called with if_num==0, won't it decrement
it to -1, and then loop 2^32 times before giving up?
