From d3dcc077bf88806201093f86325ec656e4dbfbce Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Fri, 8 Dec 2006 17:05:13 -0800 Subject: [PATCH] [NETLINK]: Put {IFA,IFLA}_{RTA,PAYLOAD} macros back for userspace. GLIBC uses them etc. They are guarded by ifndef __KERNEL__ so nobody will start accidently using them in the kernel again, it's just for userspace. Signed-off-by: David S.
