Subject: [PATCH net-2.6.25 4/4] net/netfilter - Convert IP4 address class
	macros to inline functions

Change LOOPBACK MULTICAST LOCAL_MCAST BADCLASS and ZERONET
macros to inline functions is_ip4_[type](__be32 addr)

Adds some type safety and arguably some readability

No change in compiled image size
