Log message:
	Explicitly bind the transmission of unicast packets to a network
	interface in case we need to do so.
	We need to bind to an interface only if we might be running multiple
	XORP instances. The heuristic for that is to test whether the
	unicast forwarding table ID is configured.
	
	Note that the bind mechanism is setsockopt(SO_BINDTODEVICE) which
	currently exists only on Linux.
	
	Also, note that we don't need to use the above mechanism in case of
	multicast packets, because we use setsockopt(IP_MULTICAST_IF)
	for multicast.
