  Modified files:
    sys/netinet          ip_input.c 
  Log:
  Fix an out of bounds write during the initialization of the PF_INET protocol
  family to the ip_protox[] array.  The protocol number of IPPROTO_DIVERT is
  larger than IPPROTO_MAX and was initializing memory beyond the array.
  Catch all these kinds of errors by ignoring protocols that are higher than
  IPPROTO_MAX or 0 (zero).
  
  Add more comments ip_init().
