  Modified files:
    sys/netinet          ip_output.c 
  Log:
  In the case the destination of a packet was changed by the packet filter
  to point to a local IP address; and the packet was sourced from this host
  we fill in the m_pkthdr.rcvif with a pointer to the loopback interface.
  
  Before the function ifunit("lo0") was used to obtain the ifp.  However
  this is sub-optimal from a performance point of view and might be dangerous
  if the loopback interface has been renamed.  Use the global variable 'loif'
  instead which always points to the loopback interface.
