  Modified:    sys/net   if_sl.c
  Log:
  1) Set interface up/down correctly as a function of open and close of the
     SLIP device.
  2) Don't directly frob the IFF_UP flag - use if_up/if_down as it was
     intended.
  3) Return ENETDOWN if IFF_UP isn't set when outputing, drop the packet if
     if IFF_UP isn't set when inputing.
