Subject: [PATCH net-2.6.25 2/4] net/core - Convert IP4 address class macros to inline functions

From: Joe Perches <[email-masked]>
Date: Wed, 14 Nov 2007 07:53:28 -0800

Change LOOPBACK MULTICAST LOCAL_MCAST BADCLASS and ZERONET
macros to inline functions is_ip4_[type](__be32 addr)
Adds some type safety and maybe some readability

No change in compiled image size
