Hi,
  This patches removes unused declarations in include/net/ip6_route.h
	
	1) Standlaone ip6_null_entry is no longer needed as it is replaced by
	the ip6_null_entry member of ipv6 (instance of struct netns_ipv6)	in
	struct net (as a result of Network Namespaces patches).
	
	
	2) These 3 methods from this same header are not defined anywhere:
	   ip6_rt_addr_add(), ip6_rt_addr_del(), rt6_sndmsg()

Regards,
Rami Rosen
