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.
